Microsoft Corp. was hit by a massive cloudburst today that took most of the internet services offline.
Microsoft’s Azure cloud services, as well as Teams, Office 365, OneDrive, Skype, Xbox Live, and Bing were all unavailable due to the power outage. Even the Azure Status page was reportedly taken offline.
The first reports of the power outage came from users on Twitter, and were confirmed by the website DownDetector, which showed that reports began to flow in around 5 pm ET. It says it received thousands of notifications from Xbox Live, Teams and Office users.
Microsoft’s Azure Support account on Twitter posted the following message and redirected users to an alternate Azure status page:
⚠️We are aware of an issue affecting Azure Portal and Azure Services, please visit our alternate status page here https://t.co/vGS3TQ8shs for more information and updates.

The cause of the power outage is said to be an error in the Domain Name System. The Microsoft 365 Twitter status account stated that there was a “DNS problem affecting several Microsoft 365 and Azure services” shortly after the first reports of the power outage appeared. The account then tweeted that the company was investigating a “potential DNS problem” at 176 ET
At 6 pm ET, the Microsoft 365 status account sent another tweet, saying that Microsoft “is considering our mitigation options”.
At 6.30 pm, it looked as if Microsoft would regain control of the situation. The Azure status page was back online and showed that the power outage was a worldwide problem with “network infrastructure” down in all regions. A status message said that a subset of users may experience “periodic issues” with the company’s services.
At the time of writing, Microsoft seemed to be recovering from the power outage. Microsoft 365’s Twitter status account released another update at 6:15 p.m. ET, saying that traffic was redirected to resilient DNS capabilities and that it already “saw an improvement in service availability.”
Microsoft redirected traffic to our robust DNS features and saw improvements in service availability. We are continuing to investigate the cause of the DNS issue. The next update will be given in 60 minutes or as events indicate.

It seems that Microsoft has dealt with the problem quickly, but the power outage is still a great embarrassment for the company, just two weeks after a similar incident. On March 15, Microsoft Azure was also hit by a power outage, which resulted in Office 365, Teams and Xbox Live all being taken offline for about four hours.
Microsoft blamed the problem on “a recent change to an authentication system”.
