We are currently investigating issues with Application Insights. Any customers attempting to regenerate Instrumentation Keys will see a spinning wheel; the command will fail and the Instrumentation Keys will *not* be updated. Because the command fails, attempting to regenerate Instrumentation Keys will not affect running services. Existing keys with existing agents are unaffected.
The DevOps team understands root cause and is working to deliver a hotfix before 23:00 UTC. We will provide an update once the fix is deployed or if a delay is necessary.
Thank you,
The Application Insights Service Delivery Team
