- **resolved** 2021-07-14 03:58 UTC: Relay cluster in Mumbai (GCP region asia-south1-a) is now fully operational.
- **postmortem** 2021-07-29 18:33 UTC: \*\*Components impacted\*\* Relay \*\*Summary\*\* We encountered an issue during an upgrade to our relay cluster monitoring infrastructure. As a result, we were unable to bring the Mumbai regional cluster up during this maintenance window, and so it was left down. There was no customer impact as any connections were re-routed to another relay cluster. \*\*Root cause\*\* We determined that the root cause was a configuration error introduced during a deployment configuration upgrade. This was fixed and the cluster was brought back up during a low traffic period at the end of the day. \*\*Corrective actions\*\* We identified an issue in our CI/CD process that resulted in the initial misconfiguration, which has been corrected.
