Latest Message<\/th>\nTitle: Users were unable to access the admin center and the Entra portal<\/p>\n

User impact: Users were unable to access the admin center and the Entra portal.<\/p>\n

More info: Some users would have also experienced intermittent issues accessing some Microsoft 365 services.
Users were also unable to access their cloud PCs via the Windows app web client.<\/p>\n

Final update: The failover of the Microsoft 365 portal service is complete, and we’ve validated that the service has fully recovered. Some of the affected users have also confirmed resolution.<\/p>\n

Preliminary Root cause: We identified that the Azure front Door (AFD) service had a significant loss of capacity within the Europe and Africa regions, which resulted in impact to some of the Microsoft 365 services.<\/p>\n

Scope of Impact: Any users attempting to access the Microsoft 365 admin center or leverage Microsoft Entra to access other Microsoft 365 services would have been impacted.<\/p>\n

Start time: Thursday, October 9, 2025, at 7:55 AM UTC<\/p>\n

End time: Thursday, October 9, 2025, at 11:15 AM UTC<\/p>\n

Next steps:
– We’re analyzing data from the AFD service telemetry to identify the next actions required to improve resilience within the service to avoid recurrence.<\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
