Our logs show the incident started on 02/11, 11:40 PM UTC and that during the 1 hours that it took to resolve the issue customers in the West US 2 Region with workspace-enabled Application Insights resources experienced intermittent data gaps and latent data as well as possible misfiring of alerts based on such data gaps or latencies.
  • Root Cause: The failure was due to a backend resource that hit an operational threshold.
