Azure is back online – Here is what went down [Event Timeline]

As we reported earlier today Microsoft Azure services stopped responding for many users earlier today. The outage lasted for several hours, it was initially reported as Europe only and then quickly changed to be a global issues.

Microsoft has issued the following statement :-

Starting approximately at 11:45 UTC on 30th July 2024, a subset of customers may have experienced issues connecting to Microsoft services all around the world.

Current Status: 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.

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.

We will provide an update on our continued mitigation efforts by 19:00 UTC, or sooner if we have progress to share.
