“Monitoring telemetry shows improvement in service availability, and we’re continuing to monitor to ensure full recovery.”
16:42 UTC: Root Cause: Azure Front Door Service Experiences Performance Issues Due to Usage Spike
An unexpected surge in usage has led to performance degradation in Azure Front Door (AFD) components, causing intermittent errors, timeouts, and latency spikes. In response, the Azure team implemented network configuration changes and performed failovers to alternative network paths to mitigate the impact.
Monitoring telemetry has indicated an improvement in service availability starting from approximately 14:10 UTC. However, some specific services and regions continue to report intermittent errors. The Azure team is actively investigating these issues and will provide an update on the ongoing mitigation efforts by 18:00 UTC, or sooner if significant progress is made.
“An unexpected usage spike resulted in Azure Front Door (AFD) components performing below acceptable thresholds, leading to intermittent errors, timeout, and latency spikes.”
“We have implemented network configuration changes and have performed failovers to provide alternate network paths for relief. Our monitoring telemetry shows improvement in service availability from approximately 14:10 UTC onwards, but we are investigating reports of specific services and regions that are still experiencing intermittent errors.”
“We will provide an update on our continued mitigation efforts by 18:00 UTC, or sooner if we have progress to share.” Microsoft’s new status update”
17:59 UTC: Network Configuration Changes Mitigate Usage Spike, Minimize Side Effects
Microsoft has updated that its recent network configuration changes have successfully mitigated the impacts of a usage spike that caused intermittent errors in certain services. However, the company admitted that these changes have resulted in some side effects affecting specific services and regions.
Azure team is actively updating its mitigation approach to minimize these side effects and is applying Safe Deployment Practices to ensure a smooth rollout. The updated mitigation approach will be deployed in phases, starting with the Asia Pacific regions and expanding to other areas.
“As we investigate reports of specific services and regions that are still experiencing intermittent errors, we believe that our network configuration changes have successfully mitigated the impacts of the usage spike, but that these changes are causing some side effects to certain services. We are updating our mitigation approach to minimize these side effects, and applying these following Safe Deployment Practices – beginning in Asia Pacific regions and then expanding in phases.”
