Preventing Outages in 2024

Outages have affected some of the most prominent names in the tech industry, underscoring the critical need for robust IT resilience. From AWS’s trio of outages in December 2021 to the major disruption in October 2021 that brought down Facebook, Instagram, WhatsApp, and related services, these incidents highlight the widespread impact outages can have. Even seemingly minor outages, such as Amazon’s search function being unavailable to 20% of global users for two days in December 2022, can disrupt key functionalities and erode user trust. Most recently, the Microsoft CrowdStrike outage in July 2024 further illustrated the vulnerability of even the most advanced IT infrastructures. In this blog learn about preventing outages in 2024.

When significant incidents like these occur, the stakes are high, affecting not only revenue and the bottom line but also a company’s reputation and brand. This is why vigilance and proactive strategies are essential. Although preventing every outage is impossible, the right measures can significantly mitigate their impact. This article explores six critical lessons learned from recent failures and offers practical advice to help organizations enhance their IT resilience and avoid becoming the next headline.

 

1. Monitor What Matters

Understanding that not everything is within our control is crucial. IT teams often focus on the elements they can directly influence, such as containers, VMs, hardware, and code. While this is important, it’s equally vital to monitor the entire system, including components beyond immediate control. Issues can arise in third-party services like CDNs, managed DNS, and backbone ISPs, which can impact users and the business. Developing a comprehensive Internet Performance Monitoring (IPM) strategy that includes monitoring output and performance is essential. This approach ensures that even external factors affecting user experience are under surveillance, enabling prompt detection and resolution of issues.

 

2. Map Your Internet StackPreventing-Outages-in-2024-Middle-image-

A common misconception is that unchanged components will continue to function flawlessly. However, the internet’s infrastructure, including DNS, BGP, TCP configurations, SSL, and networks, is complex and interconnected. Over-reliance on cloud services can obscure the underlying network’s visibility, making problem detection challenging. Continuous monitoring of these critical elements and having a well-prepared response plan are crucial. Teams must practice their responses regularly to maintain muscle memory, ensuring quick and efficient resolution when issues arise.

 

3. Intelligently Automate

Automation has revolutionized IT operations, enhancing efficiency and reducing errors. However, it’s essential to apply the same rigor to automation as to production systems. Design flaws in automation scripts, like those seen in the Facebook outage of October 2021, can lead to significant disruptions. Thorough testing and design consideration for potential failures are necessary to ensure robust automation. Integrating comprehensive testing into the automation design and implementation processes helps prevent surprises and minimizes risks.

 

4. Trust and Verify

Relying on multiple vendors and teams for critical operations necessitates a “trust and verify” approach. Changes made by one team or vendor can inadvertently impact others, spreading issues across the system. Understanding the dependencies within your Internet Stack is vital. Regularly verifying the plans and changes implemented by vendors ensures that your operations remain unaffected by external changes. This proactive approach helps identify and mitigate potential risks before they escalate into full-blown outages.

 

5. Implement an Internet Performance Monitoring Plan

A well-defined Internet Performance Monitoring (IPM) plan is crucial for maintaining system reliability. Establishing performance baselines before changes allows for accurate comparisons and trend analysis. This approach helps detect issues like increased latency, dropped connections, or slower DNS lookups early. Monitoring both internal and external environments ensures comprehensive visibility into system performance from the user’s perspective. This holistic approach to monitoring provides a 360-degree view, helping identify and address performance issues promptly.

 

6. Practice, Practice, Practice

The most critical lesson is the importance of regular practice. Ensuring teams are prepared for failures involves more than just having a plan. Regularly practicing crisis response, designing robust playbooks, and planning for vendor outages are essential steps. Turning practice sessions into engaging, game-like scenarios can help teams remain sharp and responsive during actual outages. This proactive preparation minimizes response times and reduces the mean time to repair (MTTR), ensuring swift recovery from disruptions.

 

Conclusion

Preventing outages in 2024 requires a multifaceted approach that includes monitoring, mapping, automation, verification, and continuous practice. By learning from past failures and implementing these strategies, organizations can enhance their IT infrastructure’s resilience and reliability, ensuring smooth operations and uninterrupted user experiences.

The recent outages among major tech giants highlight the critical importance of robust IT resilience. Events like AWS’s outages, Facebook’s October 2021 disruption, Amazon’s search functionality issue, and the recent Microsoft CrowdStrike outage in July 2024 demonstrate that no company is immune to these incidents.

CrowdStrike vs. Delta: Who’s to Blame for the Global Tech Outage?

A heated legal battle has erupted between cybersecurity giant CrowdStrike and Delta Air Lines over a recent global technology outage that caused major disruptions worldwide. The outage, which many initially attributed solely to a flawed software update from CrowdStrike, left Delta struggling to recover, resulting in the cancellation of about 5,000 flights, roughly 37% of its schedule, over four days. Crowdstrike vs. Delta: Who’s to blame for the global tech outage?

 

Delta Points Fingers, CrowdStrike Pushes Back

Delta’s chief executive, Ed Bastian, estimated that the outage cost the airline $500 million, covering expenses like compensation and hotel stays for affected passengers. Delta has since hired Boies Schiller Flexner, a prominent law firm, to pursue legal claims against CrowdStrike.

In a letter to Delta, CrowdStrike’s lawyers from Quinn Emanuel Urquhart & Sullivan pushed back against the airline’s claims. They emphasized that while the software update did cause disruptions, many other businesses, including several airlines, managed to recover within a day or two. Delta, on the other hand, faced prolonged issues, with about 75% of its remaining flights delayed.

 

Breakdown in Communication

CrowdStrike apologized for the inconvenience caused and highlighted their efforts to assist Delta’s information security team during the outage. They noted that their CEO had offered on-site help to mitigate the damage, but Delta did not respond to or accept the offer. CrowdStrike’s letter also questioned why Delta’s recovery lagged behind other airlines and suggested that any liability should be limited to under $10 million.

 

 CrowdStrike-vs.-Delta-Whos-to-Blame-for-the-Global-Tech-Outage_Middle ImageInvestigation and Expert Opinions

The U.S. Department of Transportation has launched an investigation into the incident, with Secretary Pete Buttigieg pointing out that Delta might have been particularly vulnerable due to its reliance on affected software and its overloaded crew scheduling system.

Other major carriers like American and United Airlines managed to rebound more quickly. Aviation experts suggest that Delta’s strategy of leaning heavily on cancellations rather than delays, coupled with the intense activity at its main hub in Atlanta, contributed to its extended recovery time.

 

Learning from the Past

The situation echoes Southwest Airlines’ ordeal in 2022 when severe winter storms caused massive disruptions. Southwest struggled due to insufficient equipment and an overwhelmed crew scheduling system, ultimately canceling nearly 17,000 flights over ten days.

Microsoft Windows Outage 2024

Microsoft-Windows-Outage-CrowdStrike-Falcon-Sensor-Update-banner-imag

Microsoft Windows Outage: CrowdStrike Falcon Sensor Update

 

Like millions of others, I tried to go on vacation, only to have two flights get delayed because of IT issues.  As an engineer who enjoys problem-solving and as CEO of the company nothing amps me up more than a worldwide IT issue, and what frustrates me the most is the lack of clear information.

From the announcements on their website and on social media, CloudStrike issued an update and that update was defective, causing a Microsoft outage. The computers that downloaded the update go into a debug loop; attempt to boot, error, attempt repair, restore system files, boot, repeat.

The update affects only Windows systems, Linux and Macs are unaffected.

The wide-spread impact and Windows server down focus; is because Microsoft outsourced part of their security to Cloudstrike, allowing CloudStrike to directly patch the Windows Operating System.

 

Microsoft and CrowdStrike Responses

Microsoft reported continuous improvements and ongoing mitigation actions, directing users to its admin center and status page for more details. Meanwhile, CrowdStrike acknowledged that recent crashes on Windows systems were linked to issues with the Falcon sensor.

The company stated that symptoms included the Microsoft server down and the hosts experiencing a blue screen error related to the Falcon Sensor and assured that their engineering teams were actively working on a resolution to this IT outage.

There is a deeper problem here, one that will impact us worldwide until we address it.  The technology world is becoming too intertwined with too little testing or accountability leading to a decrease in durability, stability, and an increase in outages.

 

Global Impact on Microsoft Windows UsersMicrosoft-Windows-Outage-CrowdStrike-Falcon-Sensor-Update-middle-image 

Windows users worldwide, including those in the US, Europe, and India, experienced the Windows server outage or Windows server downtime, rendering their systems unusable. Users reported their PCs randomly restarting and entering the blue screen error mode, interrupting their workday. Social media posts showed screens stuck on the recovery page with messages indicating Windows didn’t load correctly and offering options to restart the PC.

 

If Microsoft had not outsourced certain modules to CloudStrike, then this Windows server outage wouldn’t have occurred. Too many vendors build their products based on assembling a hodgepodge of tools, leading to outages when one tool fails.

The global IT outage caused by CrowdStrike’s Falcon Sensor has highlighted the vulnerability of interconnected systems, especially during Windows server downtime.

I see it in the MSP industry all the time; most (if not all) of our competitors use outsourced support tools, outsourced ticket systems, outsourced hosting, outsourced technology stack, and even outsourced staff. If everything is outsourced, then how do you maintain quality?

We are very different, which is why component outages like what is occurring today do not impact us. The tools we use are all running on servers we built, those servers are running in clusters we own, which are running in dedicated data centers we control. We plan for failures to occur, which to clients translates into unbelievable uptime, and that translates into unbelievable net promotor scores.

The net promotor score is an industry client “happiness” score; for the MSP industry, the average score is 32-38, but at Protected Harbor, our score is over 90.

Because we own our own stack, because all our staff are employees with no outsourcing, and because 85%+ of our staff are engineers, we can deliver amazing support and uptime, which translates into customer happiness.

If you are not a customer of ours and your systems are affected by this Windows server outage in the US, wait. Microsoft downtime will likely resolve soon when an update is issued, however, a manual update process might be required. If your local systems are not impacted yet, turn them off right now and wait for a couple of hours for Windows server outage in the US updates. For our clients, go to work; everything is functioning perfectly. If your local systems or home system are impacted, contact support, and we will get you running.

 

What went wrong and why?

On July 19, 2024, CrowdStrike experienced a significant incident due to a problematic Rapid Response Content update, which led to a Windows crash, widely recognized as the Windows Blue Screen of Death (BSOD). The issue originated from an IPC Template Instance that passed the Content Validator despite containing faulty content data. This bug triggered an out-of-bounds memory read, Windows outage cause operating systems to crash. The problematic update was part of Channel File 291, and while previous instances performed as expected, this particular update resulted in widespread disruptions.

The incident highlighted the need for enhanced testing and deployment strategies to prevent such occurrences. CrowdStrike plans to implement staggered deployment strategies, improved monitoring, and additional validation checks to ensure content integrity. They also aim to provide customers with greater control over content updates and detailed release notes. This incident underscores the critical need for robust content validation processes to prevent similar issues from causing outages, such as the one experienced with Microsoft.

 

Preventing Outages with High Availability (HA)

Preventing-outages-with-High-Availability-Banner-image

Preventing Outages with High Availability (HA)

High Availability (HA) is a fundamental part of data management, ensuring that critical data remains accessible and operational despite unforeseen challenges. It’s a comprehensive approach that employs various strategies and technologies to prevent outages, minimize downtime, and maintain continuous data accessibility. The following are five areas that comprise a powerful HA deployment.

Redundancy and Replication:  Redundancy and replication involve maintaining multiple copies of data across geographically distributed locations or redundant hardware components. For instance, in a private cloud environment, data may be replicated across multiple availability data centers. This redundancy ensures that if one copy of the data becomes unavailable due to hardware failures, natural disasters, or other issues, another copy can seamlessly take its place, preventing downtime and ensuring data availability. For example: On Premise Vs private cloud (AWS) offers services like Amazon S3 (Simple Storage Service) and Amazon RDS (Relational Database Service) that automatically replicate data across multiple availability zones within a region, providing high availability and durability.

Fault Tolerance:  Fault tolerance is the ability of a system to continue operating and serving data even in the presence of hardware failures, software errors, or network issues. One common example of fault tolerance is automatic failover in database systems. For instance, in a master-slave database replication setup, if the master node fails, operations are automatically redirected to one of the slave nodes, ensuring uninterrupted access to data. This ensures that critical services remain available even in the event of hardware failures or other disruptions.

Automated Monitoring and Alerting:  Automated monitoring and alerting systems continuously monitor the health and performance of data storage systems, databases, and other critical components. These systems use metrics such as CPU utilization, disk space, and network latency to detect anomalies or potential issues. For example, monitoring tools like PRTG and Grafana can be configured to track key performance indicators (KPIs) and send alerts via email, SMS, or other channels when thresholds are exceeded or abnormalities are detected. This proactive approach allows IT staff to identify and address potential issues before they escalate into outages, minimizing downtime and ensuring data availability.

For example, we write custom monitoring scripts, for our clients, that alert us to database processing pressure and long-running queries and errors.  Good monitoring is critical for production database performance and end-user usability.

Preventing-outages-with-High-Availability-Middle-imageLoad Balancing:  Load balancing distributes incoming requests for data across multiple servers or nodes to ensure optimal performance and availability. For example, a web application deployed across multiple servers may use a load balancer to distribute incoming traffic among the servers evenly. If one server becomes overloaded or unavailable, the load balancer redirects traffic to the remaining servers, ensuring that the application remains accessible and responsive. Load balancing is crucial in preventing overload situations that could lead to downtime or degraded performance.

Data Backup and Recovery:  Data backup and recovery mechanisms protect against data loss caused by accidental deletion, corruption, or other unforeseen events. Regular backups are taken of critical data and stored securely, allowing organizations to restore data quickly in the event of a failure or data loss incident.

Continuous Software Updates and Patching:  Keeping software systems up to date with the latest security patches and updates is essential for maintaining Data High Availability. For example, database vendors regularly release patches to address security vulnerabilities and software bugs. Automated patch management systems can streamline the process of applying updates across distributed systems, ensuring that critical security patches are applied promptly. By keeping software systems up-to-date, organizations can mitigate the risk of security breaches and ensure the stability and reliability of their data infrastructure.

Disaster Recovery Planning:  Disaster recovery planning involves developing comprehensive plans and procedures for recovering data and IT systems in the event of a catastrophic failure or natural disaster. For example, organizations may implement multi-site disaster recovery strategies, where critical data and applications are replicated across geographically dispersed data centers. These plans typically outline roles and responsibilities, communication protocols, backup and recovery procedures, and alternative infrastructure arrangements to minimize downtime and data loss in emergencies.

We develop database disaster automatic failure procedures and processes for clients and work with programmers or IT departments to help them understand the importance of HA and how to change their code to optimize their use of High Availability.

An Essential Tool

Data High Availability is essential for preventing outages and ensuring continuous data accessibility in modern IT environments. By employing the strategies we outlined, you can mitigate the risk of downtime, maintain business continuity, and ensure the availability and reliability of critical data and services.

High Availability is available on all modern database platforms and requires a thoughtful approach. We’d be happy to show you how we can help your organization and make your applications and systems fly without disruption. Call us today.

Why Do My Servers Keep Crashing?

Why Do My Servers Keep Crashing banner

Why Do My Servers Keep Crashing?

An organization’s worst fear is to have a server failure where essential data may be lost forever leaving your organization unable to function properly.

According to research, server failure rates rise noticeably as they age. The failure rate for a server within its first year is 5%, compared to a four-year-old server’s yearly failure frequency of 11%. Understanding server failure rates is helpful as it enables a more effective risk management as well as long-term planning for server administration and maintenance expenses.

Dealing with a server crash is never enjoyable. Users may encounter significant disruptions if a large company’s server collapses, resulting in significant financial loss. If your host’s server crashes and you are an individual with a single website, you are at the mercy of the host leaving you to pace away until the problem is fixed.

A server crashing is bound to happen at some point time so it’s a good thing to note what exactly a server crash is and why it happens.

What is a Server Crash?

A server crash is a catastrophic failure of a server that can affect the entire operation of a business as well as cause a severe financial loss. Server crashes usually occur when a server goes offline, preventing it from performing its tasks. There can be issues with the server’s numerous built-in services once it crashes. Additionally, the impact will be more significant, and the repercussions will be more severe because the server serves many customers.

  • Video Website: A significant accessibility issue within a video website makes it impossible to watch any online videos. It would be a catastrophe if the server’s data was lost and many writers’ original animations and movies could not be recovered.
  • Financial system: A rock-solid server is necessary for a financial plan that processes millions of transactions every second. Since everyone’s capital exchanges were impacted, the loss is incalculable.
  • Competitive games: There may be tens of millions of participants online for most popular and competitive games. There will undoubtedly be a lot of upset gamers if they were all disconnected from their beloved game.
    Why Do My Servers Keep Crashing middle

Reasons for Server Crash

A server may go down for various reasons, including occasionally, a single fault or multiple problems co-occurring at other times.

The following are the most typical reasons for server crashes:

  • Startup Failure: This is the most common reason for a server crash. When your server starts up, the code must run before it starts doing its job. If some of these steps fail, your server will not start properly.
  • A Software Error: The most common reason for a server crash is an application error, such as an unexpected exception or an operation that cannot be completed because of execution limits on the system.
  • A Hardware Failure (such as a power outage): If the cause of your crash is a power outage, there may be no way to recover without restoring your backup data. If this happens, you should contact your hosting service provider and ask them what steps they recommend to restore service.
  • Errors in Configuration Files or Other System Files: Sometimes errors occur in configuration files or other system files that result in incomplete or incorrect actions being taken by your application when it starts up, which can lead to crashes.
  • Security Vulnerabilities: Security vulnerabilities are typically caused by hackers, allowing them access into your server. If you have a secured server, you should not be worried about this problem as your server is well protected from hackers.
  • Overheating: If the server cannot keep itself cool, it will be unable to function correctly. If a server has an overheating problem, the system will shut down and restart itself. This may be caused by a faulty fan or power supply unit (PSU).
  • Virus Attacks: Viruses can cause server crashes in many ways. One way is that they can infect your server’s operating system or hardware and cause it to crash when it tries to process requests from the internet. Another way is that they make your computer run slowly and eventually crash, which causes fewer requests for content from your server and makes it more likely that its hard drive will run out of space and have to be replaced.
  • Expired Domain: Domain names are like URLs (uniform resource locators) for websites, but they have expiration dates set by the Internet Corporation for Assigned Names and Numbers (ICANN). When the expiration date passes, the domain name becomes available again, so any website using that domain must be changed manually. This can cause issues when your site goes offline due to a server crash because you no longer have access to the proper domain name.
  • Plug-in Error: This happens when a server gets stuck in some loop and cannot exit it because it gets stuck in an infinite loop. For example, if you have two routers connected with a switch between them, but only one router works appropriately while the other one doesn’t, then both will be affected by this issue. If you don’t want this to happen, make sure both routers have enough power or buy a new one.

Server Crashes: Numerous Causes, Numerous Solutions

No two servers are the same and they all tend to crash for a variety of reasons. While some of them we have slight control of, others are out of our hands. There are, nevertheless, precautions we may take to reduce the risk. Although they aren’t impenetrable precautions, they can mitigate end-user disruptions and downtime.

How to Prevent Crashes and Outages?

Today’s workforce relies heavily on computers for day-to-day tasks. If a computer crashes, we tend to get more than just a little agitated.

Fear of being unable to work and get our jobs done for the day races through our minds while anger takes its place in the forefront of trying to fix whatever went wrong, throwing all logic out the window.

When a system abruptly ceases to work, it crashes. The scope of a system failure can vary significantly from one that affects all subsystems to one that is just limited to a particular device or just the kernel itself.

System hang-ups are a related occurrence in which the operating system is nominally loaded. Still, the system stops responding to input from any user/device and ceases producing output. Another way to define such a system is as frozen.

This blog will explain how to prevent crashes and outages in 6 easy steps.

 

What is a System Crash and an Outage?

A system crash is a term used to describe a situation in which a computer system fails, usually due to an error or a bug in the software. An outage may also be caused by an application program, system software, driver, hardware malfunction, power outage, or another factor.

“A system freeze,” “system hang,” or “the blue screen of death” are the other terms for a system crash.

An outage is a general term for an unexpected interruption to a service or network. Outages can be planned (for example, during maintenance) or unplanned (a fault occurs). Outages can last for minutes, hours, days, or even weeks.

 

Main Reasons for Crashes and Outages

System outages can be caused by various factors, from hardware failures to software glitches. In many cases, outages are the result of a combination of factors. The following are some of the most common causes of system outages:

  • Hardware failures: A defective component can cause an entire system to fail. Servers, hard drives, and other components can fail, leading to an outage.
  • Software glitches: Software glitches can also cause system outages. A coding error or a bug in the software can disrupt the system’s regular operation.
  • Power outages: A power outage can cause the entire system to fail. The system may be damaged permanently if the power is not restored quickly.
  • Natural disasters: Natural disasters such as hurricanes, tornadoes, and earthquakes can damage or destroy critical components of the system.

System crashes can be caused by various things, from software defects to hardware failures. Sometimes, the crash may even be caused by something as simple as a power outage or due to a more severe issue, such as a virus or malware infection.

  • Overheating: When a computer’s CPU or graphics card gets too hot, it can cause the system to freeze or crash. This is often the result of inadequate cooling or dust and dirt buildup inside the computer.
  • Bad drivers: If a driver is outdated, corrupt, or incompatible with the operating system, it can cause the system to crash. In some cases, this can even lead to data loss or permanent damage to the computer.

On Tuesday, December 7, large parts of the internet and apps reported disrupted services based on the AWS platform. Netflix, Alexa, Disney+, Reddit, and IMDB are some of the services reported downtime.

UPDATE: 19:35 EST/16:35 PST, The official Amazon Web Services dashboard published the following affirmation. ” With the network device problems resolved, we are now operating towards the recovery of any impaired services. We will roll out additional updates for impaired services within the connected entry in the Service Health Dashboard.

AWS down

Users began reporting issues around 10:45 AM ET on Tuesday about the outage and took to Twitter and other social media platforms to discuss. More than 24,000 people reported cases with Amazon, which included Prime Video and other services, on DownDetector.com. The website collects outage reports from multiple sources, including user-submitted errors.

The AWS global outage recovery problems came from the US-EAST-1 AWS region in Virginia, so users elsewhere may not have noticed as many issues, and even if you were affected, you might have seen a slightly slower loading time while the network redirected your requests.

Peter DeSantis, AWS’ vice president of infrastructure, led a 600-person internal call about the then-ongoing outage. Some said it was likely an internal issue, and others pointed to more nefarious possibilities.
“We have mitigated the underlying issues that caused network devices in the US-EAST-1 Region to be impaired,” AWS said on its status page.

What caused the outage?

Engineers at Amazon Web Services (AWS), the enormous cloud computing provider in the US, are still unsure of AWS global outage causes on December 7. AWS does not list any issues on the status page currently. Previous outages have also not been reflected on the status page or even brought down the site entirely, so it is not unusual.
There is, however, a 500 Server error on the specific page for the us-east-1 AWS Management Console Home, instead of information about the Northern Virginia region.

A 500 server internal error means their server is trying to show the requested web page (the technical answer is delivered rather than the web page). But it can’t show the webpage because something within the server failed – for example, the storage failed, so the file is unavailable.

“Possible causes are internal routing problems within Amazon, a defective Amazon-wide update, an Amazon-wide misconfiguration. A defective API (application programming interface) or network device issue might also be a cause of the amazon console down,” said Richard Luna, CEO, Protected Harbor.

Amazon global outage comes just a few months after Meta Platforms, Inc. (FB) went offline due to network problems, affecting some of its most popular apps, including WhatsApp, Instagram, and Facebook Messenger.
The research firm Gartner Inc. estimates that major cloud platforms suffer significant outages once per quarter per year. Many people felt the AWS service disruption; however, since AWS controls about 90% of the cloud infrastructure market and many people continue to work and study from home during the pandemic, the outage was widely felt. Gartner vice president Sid Nag told The Wall Street Journal that these guys have become almost too big to fail. Our day-to-day lives rely heavily on cloud computing services.

 

Hasn’t This Happened Before?

Yes, AWS downtime is not a new occurrence. The last major AWS global outage happened in November 2020. Numerous other disruptive and lengthy cloud service interruptions have involved various providers. In June, the behind-the-scenes content distributor Fastly experienced a failure that briefly took down dozens of major internet sites, including CNN, The New York Times, and Britain’s government home page. Another cloud service interruption that month affected provider Akamai during peak business hours in Asia.

In the October outage, Facebook — now known as Meta Platforms — blamed a “faulty configuration change” for an hours-long worldwide AWS downtime that took down Instagram and WhatsApp in addition to its titular platform.

 

Credible solutions

On Tuesday, the world received a reminder of just how much we rely on Amazon Web Services and AWS global outage recovery. A simple outage for a brief period disrupted the operations and services of millions of people. Amazon is in the monopoly and would never partner with another provider. So the simplest solution is to opt for a service provider who puts customers first.

Amazon, as big it is, is still just one location and provides a single server location to the clients. At its core, it is one batch of servers. Protected Harbor solves this problem by spreading the customers across multiple server locations, preventing a site-wide misconfiguration. We protect our clients by using various services; we expect one service to fail- that gives us time to resolve and repair the situation quickly.

We differentiate from other providers by being proactive and planning for failures like this. We do it all the time- partner with other providers to deliver unmatched services to the customers because their satisfaction comes first.

 

Key Takeaways:

  • An hours-long AWS outage crippled popular websites and disrupted smart devices, as well as creating delivery delays at Amazon warehouses.
  • Companies like Facebook, Netflix, Reddit, IMDB, Disney+, and more were affected by the outage.
  • Amazon stated that it “identified the root cause” but yet to reveal what precisely the root cause was?
  • AWS controls almost 90% of the cloud services market, and the outages are not uncommon.
  • Now is the time to choose the provider which satisfies you and your business needs.

Go complete risk-free

Protected Harbor is the underdog player in the market that exceeds the customer’s expectations. With its Datacenter and Managed IT services, it has stood the test of customers, and “Beyond expectations” is quoted by all customers. Best in segment cloud services with optimum IT support, safety, and security, it’s a no-brainer why organizations choose to stay with us. This way to the crème de la crème.

Facebook Down Globally: A Case of the Mondays for Facebook, Instagram, and WhatsApp as they go dark midday Monday

 

Some of the biggest social media sites on the planet, including Facebook, went down globally starting at noon EDT and are still not up in some regions. That’s right, no Instagram #motivationmondays or “Ugh, is it Friday Yet?” Facebook posts from your first semester freshman year college roommate. As the sky was falling for millennials (myself included) and your favorite newly-political aunt, the teams at Facebook were scrambling to keep their sites (including Instagram and WhatsApp, of which both are Facebook-owned) operating.

Facebook Chief Technology Officer Mike Schoepfer took to Twitter to address the situation:

“*Sincere* apologies to everyone impacted by outages of Facebook-powered services right now. We are experiencing networking issues and teams are working as fast as possible to debug and restore as fast as possible”

Facebook outages of this magnitude are rare, to have Facebook down globally for this amount of time is something that hasn’t happened in years. To put in perspective just how impactful the Facebook outage is, the term “Facebook down” was Googled more than 5,000,000 times today alone.
The cause of the outage is speculated to be tied to a recently aired “60 Minutes” segment where whistleblower and former Product Manager at Facebook, Frances Haugen claimed that Facebook knows the platform is used to spread hate and that they have tried hiding evidence of it, of course, Facebook denies this claim.

“The interview followed weeks of reporting about and criticism of Facebook after Haugen released thousands of pages of internal documents to regulators and the Wall Street Journal. Haugen is set to testify before a Senate subcommittee on Tuesday.” According to CNN

Jake Williams, CTO of cybersecurity firm BreachQuest mentioned to the Associated Press that this was an “operational issue” caused by human error.

Regardless of the reasoning, I’m sure this will be an issue that will be discussed for quite some time in the technology space as the outage was global and not regional. Facebook shares opened at $335.50 and closed at $326.32, a drop of 4.89%.

Nonetheless, as I’m sure many were beside themselves that they couldn’t post a nice “Los Angeles” filtered photo of their lunch on Instagram to show their followers, we can only hope, for Facebook’s sake, they can have it fixed by the time we want to show off our dinner.

It has been confirmed that per a Facebook blog that the outage was due to a botched configuration change. Facebook posted the following:

Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centers caused issues that interrupted this communication. This disruption to network traffic had a cascading effect on the way our data centers communicate, bringing our services to a halt.”

Information about the depth of the outage continues to grow, it’s reported that Facebook’s internal chat was also down limiting communications within the company, it even went so far as the employee’s keycards began to fail which made them unable to enter certain buildings.

The Krebs on Security blog explains the problem as follows:

“…sometime this morning Facebook took away the map telling the world’s computers how to find its various online properties. As a result, when one types Facebook.com into a web browser, the browser has no idea where to find Facebook.com, and so returns an error page.”

The Facebook campus was only the beginning, due to the sites interconnectivity it stretched to sites that were utilizing Facebook’s authentication process as well, these effects resonated across the board, from those who rely on Facebook/WhatsApp for primary communication purposes, to small businesses unable to get in touch with their customer base, and even the large number of folks in countries where Facebook is their internet.

We will continue to update as information becomes available.
