Microsoft 365 Also Down
Microsoft is also investigating access issues and degraded performance affecting several Microsoft 365 services and features. The incident, identified as MO842351, is under review, with detailed information available in the admin center for those impacted.
Current Status
As of the last update at 13:13 UTC on July 30, 2024, the investigation was ongoing, and Microsoft promised to provide more details as soon as possible. The company has mitigated and rerouted user requests to address the issue and is actively monitoring the situation.
Root Cause and Mitigation Efforts
An unexpected surge in usage caused performance degradation in Azure Front Door components, causing intermittent errors, timeouts, and latency spikes. The Azure team implemented network configuration changes and performed failovers to mitigate the impact. Monitoring telemetry showed improvement in service availability from 14:10 UTC, but some services and regions still report intermittent errors. The team is actively investigating and will provide an update on mitigation efforts by 18:00 UTC or sooner if significant progress is made.
Next Steps
Microsoft has confirmed that recent network configuration changes have successfully mitigated the effects of a usage spike causing intermittent errors in certain services. However, the company acknowledges that these changes have caused side effects in specific regions.
The Azure team is updating its mitigation approach to minimize these effects and is applying Safe Deployment Practices for a smooth rollout.
