At about 02:45 UTC on August 10, 2022, we observed the Channel Groups service reporting errors in our Mumbai PoP, preventing users from making channel group related API calls there. We contacted our third-party vendor where the affected node resides, and the vendor applied a fix resolving the issue at 03:20 UTC. This issue occurred because of an error in our vendor's configuration that went undetected.
To prevent a similar issue from occurring in the future we have confirmed that our vendor has applied a fix which addressed the root cause.
