Understanding the Root Cause
What Caused This Microsoft 365 Outage?
Microsoft has identified several potential contributing factors behind the current service disruption:
- Azure Front Door Routing Issues: The outage appears to be linked to a faulty routing configuration in Azure Front Door (AFD), which is critical for content delivery and server communications.
- High CPU Usage: A segment of the AFD infrastructure is experiencing abnormally high CPU utilization, leading to performance degradation below acceptable thresholds.
- Traffic Rerouting: In an effort to mitigate the impact, Microsoft has initiated traffic rerouting to alternate infrastructure, though some services remain unstable.
This outage echoes past incidents. For instance, in March, a similar outage affected Microsoft Teams and Exchange Online, leading to call failures and email issues. More details on that event can be found at BleepingComputer.
