Final Update: Thursday, 08 February 2018 01:11 UTC

We've confirmed that all systems are back to normal with no customer impact as of 02/08, 00:00 UTC. Our logs show the incident started on 02/07, 21:30 UTC and during that 2.5 hours that it took to resolve the issue , customers would have experience alerting issue i.e. notification was not received for alerts configured based on availability as well as metrics.

  • Root Cause: The failure was due to communication failures between two services which are responsible for alert rules and alerts input.
  • Lessons Learned: We understand the root caused completely and work has planned to avoid re-occurrence of this issue in future.
  • Incident Timeline:  2 Hours & 30 minutes - 02/07, 21:30 UTC through 02/08, 00:00 UTC

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

We currently have no estimate for resolution.
