Microsoft said that beginning shortly before 8 a.m. New York time on Thursday users of the Azure cloud-computing network and Microsoft 365 products might be unable to access their services through AT&T’s network.
Notices posted to Microsoft status health pages said the issue appeared to be caused by a change AT&T made. Once the telecom company reverted the update at 9:14 a.m., “we started to see signs of recovery, mitigating the issue,” Microsoft said.
AT&T didn’t immediately respond to a request for comment.
Microsoft experienced an Azure outage in July that was triggered by a distributed-denial-of-service cyberattack. During that incident, an error in Microsoft’s automated protection mechanisms worsened the impact rather than mitigating it, the company said.
Weeks earlier, some 8 million computers running on the Windows operating system crashed after the cybersecurity firm CrowdStrike Holdings Inc. released a flawed software update.
