Experiencing Alerting failure for Metric Alerts – 12/15 – Mitigating

Root cause has been isolated to new feature rollout which was causing duplicate notification when resource was unhealthy for some customer in the azure portal. Specifically, any metric alert names with non ascii characters see this impact. To address the issue, we’ve started mitigation to disable the feature. Some customers may continue to see notifications and we estimate 4 hours before all is addressed.

    Root Cause: New feature rollout which was causing duplicate notification.

    Incident Timeline:  14 day 23 hours – 12/01, 11:00 PM UTC through on going 12/15, 10:00 PM UTC

    Next Update: Before 12/16 01:30 UTC
