Azure outage disrupts access to Microsoft 365 services and admin portals
Microsoft Azure Front Door Outage: Service Restoration Update
Azure Front Door Outage Impacts Microsoft 365 Services
Microsoft has been addressing a significant outage in its Azure Front Door content delivery network (CDN) that has disrupted access to its Microsoft 365 services. Beginning at approximately 07:40 UTC, the outage caused delays and timeouts for users across Europe, Africa, and the Middle East trying to connect to the Azure and Entra portals.
Efforts to Restore Azure Services
As part of their mitigation efforts, Microsoft’s engineering teams have been restarting specific Kubernetes instances responsible for capacity loss within Azure Front Door (AFD). These efforts have been largely successful, with Microsoft reporting a 98% restoration of the AFD service while monitoring telemetry data to ensure a complete recovery.
Continuing Impact on Microsoft 365 Users
Despite significant progress, some users still experience intermittent issues in accessing certain Microsoft 365 services and cloud PCs through the Windows app web client. Initially, the Azure Front Door capacity issues affected a large number of customers, but the impact has been reduced to approximately 4% of the initially disrupted services.
