Final Update: Sunday, 11 April 2021 11:24 UTC

We’ve confirmed that all systems are back to normal with no customer impact as of 04/08, 13:45 UTC. Our logs show the incident started on 03/31, 15:45 UTC and that during the 7 days and 22 hours that it took to resolve the issue some customers may have experienced misfired alerts when using Azure Metric Alert Rules on Log Analytics resources in West Europe region.

  • Root Cause: We determined that a backend service responsible for processing alerts became unhealthy due to a configuration issue.
  • Incident Timeline: 7 Days & 22 Hours – 03/31, 15:45 UTC through 04/08, 13:45 UTC

We understand that customers rely on Metric Alerts as a critical service and apologize for any impact this incident caused.
