We've confirmed that all systems are back to normal with no customer impact as of 4/8, 16:40 UTC. Our logs show the incident started on 4/8, 14:30 UTC and that during the 2 hours that it took to resolve the issue a very small number of requests failed on the Failure and Log Search blades (approximately .02% of requests).
  • Root Cause: The failure was due to a configuration error in a back-end service.
