The Azure Front Door content delivery network (CDN) is experiencing an outage that is preventing users from accessing certain Microsoft 365 services and Microsoft is trying to fix this issue. This service outage has also denies users access to the admin centre and other services that depend on Microsoft Entra ID for authentication.
Access problems are becoming prevalent for companies that rely on Microsoft’s cloud-based productivity suite as a result of the interruption, which started on Thursday, October 9, 2025.
The problem is widespread and affects every user trying to log in with Microsoft Entra ID or access the Microsoft 365 admin centre.
Outlook, Teams, SharePoint, and many other Microsoft 365 services may not be available to end users due to this fundamental reliance.
Microsoft acknowledged that it is looking into complaints from customers who are having trouble using these important services. The investigation’s first step was to analyse dependent service paths in order to pinpoint the failure’s cause and decide on the best course of action.
The inability to access the admin centre puts IT administrators in a difficult position since it makes it impossible for them to manage their environment or solve problems that affect users.
In Europe, Africa, and the Middle East, there were delays and timeouts when attempting to connect to the Azure and Entra portals starting at approximately 07:40 UTC, according to Redmond.
AFD instances that were experiencing capacity loss have since been brought back online by the company’s engineering teams restarting Kubernetes instances.
Microsoft lists this outage on the Service Health Dashboard as a continuing event, a term frequently used for major service difficulties with noticeable user impact, even though the company has not yet revealed the number of users impacted.
“Roughly 98% of the AFD service is back online. To ensure complete recovery, we are continuously monitoring and checking with the air of telemetry. In a recent service advisory, Redmond stated, “We’re starting failover for the Microsoft 365 Portal service concurrently to speed up the restoration process.”
“Some users can also occasionally have trouble using certain Microsoft 365 services. Users may also encounter difficulties using the Windows app web client to access their cloud PCs.
Published at 12:33 UTC (almost five hours after the fault was noticed), the most recent update to the official Azure status site states that only about 4% of the customers who were initially affected are currently affected by the Azure Front Door capacity difficulties.
Microsoft claims that as they continue our mitigation efforts, we have successfully recovered 96% of impacted resources, teams are working on recovering the remaining 4% of impacted customers.
Microsoft 365 services, such as Exchange Online, Microsoft Teams, and the admin centre, were unavailable to customers globally for many hours on Wednesday until Redmond’s teams fixed the issue.
It also has fixed a similar issue in July that was blocking access to the admin centre for Microsoft 365 administrators who have business or enterprise licenses.
As of October 09, 12:07 EDT, an update from Microsoft had reported that the problem has been contained and that all impacted services have fully recovered.
And from the final update on the Microsoft 365 admin centre, “We discovered that the Azure front door (AFD) service experienced a notable loss of capacity in the Europe and Africa regions, which led to an impact on certain Microsoft 365 services.”
“We have confirmed that the Microsoft 365 portal service has fully recovered after its complete failover. A few of the impacted users have also attested to the resolution.
In order to determine the precise reason of the problem and comprehend the mechanics of the failure, the organisation is examining a large amount of diagnostic data.
Microsoft’s efforts are currently focused on the load-balancing architecture in its environment as the inquiry further develops.
Incoming network traffic must be efficiently distributed among several servers by load balancers; a malfunction in this system may be the cause of the observed sporadic connectivity problems and access failures.
In order to address the root cause and promptly restore service, the company has said that it is actively developing mitigating techniques.
As engineers continue to address the issue, Microsoft has promised to provide an update on Thursday, October 9, 2025, at 5:30 PM GMT+5:30.
