More info: Impacted services included, but were not limited to: - Microsoft 365 admin center - SharePoint Online - Microsoft Teams Final status: We've received additional reports that the issue has recovered, and telemetry that monitors CDN interactions has shown there is no longer impact. We've confirmed that a CDN endpoint became unavailable for a period of time and the cause of this is still under investigation. Our automated recovery features should have mitigated the issue without intervention by failing traffic to an alternate CDN endpoint, however, this did not occur and resulted in extended impact. We’re continuing to examine the underlying circumstances that led to this behavior to enhance the resiliency of our services. Scope of impact: Impact was specific to some users located in the North American region attempting to access the Microsoft 365 admin center, Microsoft Teams and SharePoint Online. Start time: Friday, March 6, 2026, at 1:00 PM UTC End time: Friday, March 6, 2026, at 4:55 PM UTC Next steps: - We're investigating the automated recovery features to understand why it did they not perform as expected. - We're reviewing CDN infrastructure to identify why the endpoint became unavailable. We'll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days. Is this message helpful? Did you find this email helpful?
