The issue began in the Americas and became a worldwide issue by Friday. On Friday, November 13th, it became known that the software people rely on every single day had failed to load. The huge Microsoft outage caused millions around the globe to lose access to Outlook email, Teams meeting software and other essential applications of contemporary offices, impacting financial institutions, governments and even courts around the world.
At 3:30 a.m. GMT Friday, the outage was still ongoing, impacting millions.
This problem was already started earlier. Early Thursday morning, Microsoft first mentioned that there was an investigation going on about problems associated with the functionality of Teams for customers in North America.
Initially, Microsoft stated that there were connection problems "in the Americas," but later it turned out that this problem was global. Some employees in American businesses left work early on Thursday.
Friday morning hit Australia the hardest. There could be no printing of invoices for business, and online classes could not be held in some schools.
The government authorities of the Australian Capital Territory, Tasmania and Western Australia admitted that their organizations were affected, while the South Australia and Victoria state courts indicated that there were issues in operations due to the outage.
Also, the Northern Territory Department of Education mentioned that there were technical problems in schools throughout the territory.
The damage did not stop there. Psychologists were unable to offer any telemedical services, businesses were unable to process their orders, and even some of the service centers run by the government had to close down.
It is claimed that family violence specialists couldn’t access the databases that contained the personal information of their clients, and schools were unable to give online classes to their distant students.
According to the ABC network, people were missing their job interviews because they weren’t able to join virtual meetings and there were some shortages at distribution centers of supermarkets.
It went on for quite a while. According to Microsoft, some affected services included Outlook, Teams, SharePoint Online, Microsoft 365 Copilot, Planner, Exchange Online, and Defender.
The impact extended to other businesses as well. OpenAI and Anthropic experienced issues with the services that integrated their AI solutions with Microsoft 365.
The organization has not provided much information about this issue. For example, on X, the organization stated that they were “aggressively pursuing all pathways to reduce impact” and “restarting affected servers to put them back into service.”
Recovery efforts were inconsistent. According to Microsoft, a “sustained recovery had not been observed in affected regions.” One of the updates noted that servers put back into service may go unresponsive again once they start receiving traffic; as a result, Outlook experienced another disruption.
It is worth mentioning that SBS News reported that Microsoft had quickly taken back one of the positive updates concerning the Outlook outage.
As per an official statement by a Microsoft executive, the cause for the outage did not involve a cyber attack. No such root cause had been reported by the company in the incident reports. The cause for the failure was not mentioned anywhere.
The scale of the issue drew comment regarding dependence on a few companies. One expert characterized the outages as “incredibly widespread,” with effects extending far beyond just exchanging work emails.
It is an argument that is well-known. When a few companies are responsible for the software that businesses, schools, and courts use, one problem can affect many at once.
The historical events serve as a background for understanding what happened. Thus, on July 19, 2024, there was an error in an update released by CrowdStrike, leading to crashing of around 8.5 million computers running Windows all over the world, affecting airlines, banks, and hospitals and causing damages valued at tens of billions of dollars.
There is another reason for this particular event to be cited. It was related to security software, but not a cloud provider. Thus, in January 2023, Microsoft's cloud Azure experienced a network outage that brought Teams and Outlook down, which Microsoft managed to fix by reverting to a network change.
There are several measures which will highlight the severity of this issue. Firstly, whether Microsoft recovers for good or the servers go down once again. Secondly, the time it takes for the services to become normal in every region. Lastly, the explanation provided by the company in their post-crisis report.
Other organisations who use Microsoft 365 might consider their alternative means of communication as well. According to the reports mentioned, there were cases when small companies and local governments had to resort to telephone calls.
