App deployment degradation

This issue is now resolved and performance is back to normal.
We recommend any apps deployed between 9:24 UTC on 2024-10-23
05:56 UTC 2024-10-25 to be re-deployed in case the app users identify any latency issues.

Between 08:59 UTC and 9:24 UTC on 2024-10-23 we have observed increased error rate on app deployments, similar to problem that happened on 2024-10-24.

After investigation we found an condition in one of cells in EU region which was causing deployments to fail.

We applied change to migrate new deployments off the impacted EU cell which mitigated impact.

We are keeping this incident in monitoring state and will resolve it once underlying issue is resolved and deployments are resumed to the affected cell.

From perspective of App developers this means that deployments of apps (new apps and updates to existing ones) will work correctly but may introduce minor performance degradation due to function being invoked from nearest EU cell when customer is located in the affected cell. Because of this we will post an update advising to re-deploy affected apps once this incident is resolved.
