Microsoft’s cloud-based products with Teams integration suffered an outage Wednesday night and early Thursday morning Eastern time, according to a report by Bleeping Computer news service, disrupting customers in the southern hemisphere and in Europe and Asia. It was traced to what Microsoft said on its Twitter status feed was a broken connection to an internal storage service.
We’ve determined that a recent deployment contained a broken connection to an internal storage service, which has resulted in impact. We’re working to direct traffic to a healthy service to mitigate impact. Additional information can be found in the admin center under TM402718.
