Final Update: Thursday, 27 April 2017 03:38 UTC
We've confirmed that all systems are back to normal with no customer impact as of 04/27, 03:00 UTC. However some customer might see incorrect data for request & dependency data type in Application Map if time window is selected anywhere between 04/25, 21:00 UTC and 04/27, 03:00 UTC. All other data types are unaffected.
- Root Cause: The failure was due to configuration change in system.
- Incident Timeline: 30 Hours - 04/25, 21:00 UTC through 04/27, 03:00 UTC
We understand that customers rely on Application Insights as a critical service and apologize for any impact this incident caused.
Application Insights team is mitigating an issue in our services which is caused by recent configuration change. This change has caused incorrect grouping of dependency and request data types. Some customers using Application Map might see incorrect data for the time period starting 04/25/2017 21:00 till now. We understand this issue completely and our team is working on a hotfix deployment. We provide more updates upon successful validation of deployment that we expect to be completed in next 3 hours.
- Work Around: None
