Microsoft Admin Center

User impact: Admins intermittently may be unable to access the Microsoft 365 admin center.  Current status: We're continuing to analyze the unusually large increase in requests to the Microsoft 365 admin center along with recent service updates to isolate potential sources of impact that contributed to the traffic increase. We’ve implemented performance optimizations to assist with processing affected traffic and we've validated that service availability has recovered to pre-impact levels. We're continuing our investigation in order to isolate and remediate the underlying root cause to ensure the similar scenario does not occur again in the future.  Scope of impact: Admins attempting to access the Microsoft 365 admin center may be intermittently affected. This section may be updated as the investigation progresses.  Start time: Monday, October 5, 2026, at 10:28 PM UTC  Next update by: Tuesday, October 6, 2026, at 1:30 AM UTC
