Experiencing Data Access Issue in Azure and Application Analytics Portal for Multiple Data Types – 08/29 – Resolved


Final Update: Monday, 29 August 2016 14:49 UTC

We’ve confirmed that all systems are back to normal with no customer impact as of 8/29, 13:50 UTC. Our logs show the incident started on 8/29, 09:54 UTC and that during the 4 hours that it took to resolve the issue a very small subset of customers experienced data access issues at application analytics and azure portal. There are 2 applications whose subset of data is currently being re-processed and will experience some data gaps until restore process is completed.
  • Root Cause: The failure was due to performance degradation in downstream backend service.
  • Lessons Learned: We have collected required telemetry data during the impact period which we will utilize to avoid such re-ocurrances in future.
  • Incident Timeline: 3 Hours & 54 minutes – 8/29, 09:54 UTC through 8/29, 13:50 UTC

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