OUTAGES: Some of the global cloud outages that affected the world

Outages in the cloud can be less disastrous than outages in data centers. When it comes to cloud-related concerns, providers can work with a user’s team to resolve issues, whereas data centers may require an internal staff to resolve issues. Everyone can expect more disruptions as cloud adoption and the number of regions, zones, and cloud services grow. However, he believes that the number of worldwide, all-service outages that make the news will decline.

Meanwhile, Here is a list of some of the most significant cloud outages and difficulties that have affected computers in the year 2021. Here’s everything you need to know about it.

  • Microsoft team issues in February-

The Microsoft Teams collaboration app had two different disruptions in February. First, on February 4, certain North American users were unable to join meetings due to a technical issue. “We rectified the brief interruption that a subset of customers in North America may have encountered connecting to meetings or live events,” Microsoft said in a statement released that afternoon. The Teams outage was visible on in a number of major locations across the United States and Canada, including New York, Washington, Chicago, Toronto, San Francisco, Los Angeles, Dallas, Phoenix, Atlanta, Seattle, and Boston.

On February 17, Teams was affected by a possible networking issue, which caused certain North American users to experience delays in receiving chat messages. Microsoft also acknowledged that running live events in Teams was problematic. Some users in South America were also impacted. After almost five hours, the problem with delayed chat messages was rectified. “We rerouted services to alternate infrastructure, and the impact on message delivery has been mitigated,” Microsoft said in a tweet at 4:07 p.m. ET.

  • Microsoft March Outage-

A global outage affecting the Teams collaboration app, as well as “many” additional Azure, Office 365, and Dynamics 365 services, was announced by Microsoft in March. The Teams and Azure outage was caused by “an issue with a recent modification to an authentication mechanism,” according to Microsoft. After roughly four hours, Microsoft claimed that the widespread disruption was mostly resolved. The Teams outage was visible on a map on Downdetector, affecting cities such as New York, Washington, Chicago, Toronto, San Francisco, Los Angeles, and Seattle. “The update has completed a deployment to all impacted regions,” Microsoft tweeted at 5:57 p.m. ET on March 15. Telemetry error rates in Microsoft 365 services are reducing.

  • OVHcloud is burned down on March 10, 2021. (but then files for IPO) –

The SBG2 data center of OVHcloud, Europe’s largest cloud service provider, burned down in Strasbourg, causing damage to the SBG1 data center as well. Although no one was hurt, the incident caused many clients’ websites and emails to go down. Despite this, the company decided to go public later that year.

  • Microsoft Outages in April-

“In April, three weeks after the March outage, the Redmond, Wash.-based tech giant reported that DNS difficulties caused an outage that impacted cloud services such as Azure, Teams, and Dynamics 365. After roughly five hours, the problem was completely resolved. The troubles, according to Microsoft, were caused by an unexpected rise in DNS traffic. DNS is a directory that connects domain names to their IP addresses. The problem peaked between 5:30 p.m. and 6:30 p.m. ET on April 1, and it was fully mitigated by about 10:30 p.m., according to Microsoft.

Users of the Microsoft Teams video conferencing and collaboration software were affected by a global outage on April 27. By 9:03 a.m. ET the next day, Microsoft had resolved the problem. In a statement at 6:53 a.m., Microsoft acknowledged the global outage, saying, “We’ve validated that this issue affects customers internationally.” We’re looking into monitoring telemetry and recent changes to figure out what’s causing the problem.”

  • Google Outage in April-

For around three hours in April, Google Drive and cloud-based apps like Google Docs were also unavailable, causing excessive latency and other difficulties for some users. During the partial outage on April 12, the Google Drive cloud storage service—along with linked cloud apps like Google Docs and Google Sheets—experienced several service difficulties. Other Google services, such as Gmail, Google Calendar, and Google Meet, were unaffected. While customers were still able to browse Google Drive, they were unable to create new documents and experienced “error warnings, high latency, and/or other unusual behavior,” according to the company. On the Google Drive service details page, the business said, “We regret the inconvenience and thank you for your patience and continuing support.

  • Microsoft June issues-

Microsoft, too, had some problems in June. The calling service used by the teams routed calls directly to the voicemail boxes of some consumers. On June 11, around 3 p.m. ET, the Microsoft 365 Status Twitter account announced that the company was looking into reports of incoming calls in Teams going “straight to voicemail.” Following that, Microsoft “identified a recent modification that caused portions of infrastructure to redirect some Microsoft Teams calls straight to voicemail,” according to the account. Microsoft had been “dramatically better” at alerting partners “as soon as they are aware of an issue and stating when they expect the issue to be solved—or at least provide a status,” Rosalyn Arntzen, president, and CEO of Redmond, Wash.-based Amaxra, a Microsoft Gold partner, told CRN at the time.

  • One AWS availability zone in Europe causes a stir.

Due to connectivity issues “induced by an increase in ambient temperature,” the AWS EU-Central region had a major outage in EUC AZ-1 on the 10th of June, 2021. The outage lasted three hours and was triggered by a control system malfunction that shut down multiple air handlers in the impacted Availability Zone. Isn’t it simple?

  • Facebook & Co. has had a catastrophic collapse.

The world went berserk when Facebook and its subsidiaries – Messenger, Instagram, WhatsApp, Mapillary, and Oculus – went down for 6 to 7 hours 4th of October, 2021. Many frantic users went to Twitter(read a tweet), Discord, Signal, and Telegram, causing service outages on these platforms.

  • Google Cloud discovers a networking issue on November 16, 2021.

In mid-November, Google Cloud fell down, taking with it services like Home Depot, Snap, and Spotify. What was the cause of the outage? A problem with the network settings. Another example of why relying on a single provider to manage all of your apps is a bad idea.

  • AWS us-east-1 suffers from an outage on December 7, 2021

AWS cloud unit us-east-1 experienced an outage, affecting services such as Disney+, Netflix, Slack, Ticketmaster, stock trading software Robinhood, and cryptocurrency exchange Coinbase. Internal tools used by Amazon warehouse and delivery personnel, such as the Flex and AtoZ apps, were also impacted.

SECURITY ISSUES- Cloud security vulnerabilities in 2021

  • The year 2021 finished on a high note, with the discovery of a vulnerability in the log4j open source logging library. It has a huge impact and will have long-term consequences for the industry. The Apache Log4j library is “universal” across applications, and its use allows for complete server control. The library may be found almost everywhere, including the AWS S3 storage service and software solutions you may use on a daily basis. The Log4j flaw has sent shockwaves through the tech industry. The Cybersecurity and Infrastructure Security Agency (CISA) has announced the release of a scanner for detecting web services afflicted by two Apache Log4j remote code execution flaws, dubbed CVE-2021-44228 and CVE-2021-45046.
  • Google and Oracle will compete for a cloud contract with the Pentagon. Microsoft was awarded the JEDI contract in 2019, however, it was later canceled. Google and Oracle are the only two cloud providers who might be interested in bidding for this role. Visit Cloud-computing News to read the rest of the story.
  • The Ransomware Attack on the Colonial Pipeline The Colonial Pipeline Company was hit by a ransomware-based hacking attack, forcing the company to disconnect a few frameworks and shut down the pipeline. The Georgia-based company claims to run the country’s largest oil pipeline, transporting 2.5 million barrels of gas, diesel, heating oil, and jet fuel each day from Texas to New Jersey.
  • A slew of Microsoft security flaws has been discovered. In terms of security, Microsoft has had a difficult year. Each month in 2021, the company will issue a fix for at least one zero-day flaw (except for May). Microsoft’s operating systems, platforms, and applications have certain serious flaws that might put their consumers in danger and lead to attacks on firms including SolarWinds, Colonial Pipeline, and HAFNIUM.
  • For years, Cosmos DB leaves the door open to attackers. The “worst cloud vulnerability you can imagine” was discovered in Microsoft Azure at the end of August. Customers using Cosmos DB were affected in 30 percent of cases. The service offered attackers who exploited the flaw read/write access to all databases. It had been there for “at least a few months, if not years.
  • On-premises is proving to be a risky option. When Chinese hackers are looking for loopholes, running email on your own server in 2021 is a risky business. In Microsoft Exchange, they found one. Any organization that uses a copy of the software might have been hacked — that’s over 30,000 businesses! This just goes to prove that, despite all of the other security concerns we discussed earlier, migrating to the cloud is a wise decision!
  • Data breaches at Facebook and LinkedIn have been catastrophic. A security researcher discovered a vast leaked database including the personal information of 533 million Facebook users from the United States, the United Kingdom, and India. Then someone else uncovered that the personal information of 700 million LinkedIn users (almost 93 percent of the platform’s users) was for sale on the internet.


  • Clouds that were single and private were out. According to an IBM analysis, both types of infrastructure fell from 29 % in 2019 to only 2 % in 2021. Who came out on top in the race? Multi-cloud and hybrid cloud!
  • Who is the owner of the public cloud? According to Canalys, the big three cloud providers (AWS, Microsoft Azure, and Google Cloud) account for 61% of public cloud services. AWS now accounts for 31% of global cloud infrastructure spending, bringing in $59 billion in revenue per year (more than HP or Lenovo combined!).
  • The popularity of cloud-native computing is on the rise. Many companies adopted cloud-native technologies in response to COVID-19, according to HashiCorp: Infrastructure as Code (49%) is the most popular, followed by container orchestration (41%), network infrastructure automation (33%), and self-service infrastructure (33%). (32 percent)
  • To control escalating cloud costs, companies are turning to automation. The Flexera State of the Cloud Report provided insight into how companies are managing escalating cloud costs. Many of them rely on automation, such as automated controls that shut down workloads after hours (49 percent) and virtual machine rightsizing (48 percent ). However, in 2022, they still have a long way to go.
  • Cloud and Kubernetes-related bills continue to rise, according to the CNCF and FinOps micro survey. Despite this, businesses lack the necessary tools to generate accurate estimates and avoid cloud waste. Nearly half of them stated their monitoring technique was based on guesswork, and nearly a quarter acknowledged having no solution at all.


  • AWS provided cloud services to Parler that hosted its website, meaning it would go offline unless it could locate a new cloud provider. Because Parler cannot comply with our terms of service and poses a very real risk to public safety, we plan to suspend Parler’s account effective Sunday, January 10th, at 11:59 PM PST. The year 2021 began with a bang as well. A group of Amazon employees demanded that the company’s cloud division discontinue supplying services to Parler, the social media platform utilized by rioters who stormed the US Capitol on January 6, 2021. AWS disconnected Parler, and other large providers followed suit, demonstrating their decision-making power in the process.
  • Is there anything that hasn’t changed? It’s still about the chips. The computer industry, as well as the rest of the world, faced a global chip shortage in 2021, as the pandemic-era chip supply chain just couldn’t keep up with the increased demand. Apple, BMW, and Whirlpool were among the companies affected. On the other side, a lot of effort (and money) has gone into independent chip projects, such as Apple’s M2, Amazon’s own networking chips, and Nvidia’s long-running attempt to buy Arm for $40 billion.
  • Microsoft’s JEDI contract has been canceled by the Pentagon. This contract might have been valued up to $10 billion, but the Pentagon decided to look at other cloud service providers’ offers instead, citing the changing cloud landscape as a cause. Is the Pentagon considering a multi-cloud strategy?
