Root Cause Analysis

This incident was caused by a bug in a recent change to our backend real-time messaging service that manages communication between multiple applications. The issue occurred intermittently when concurrent publishing events were handled.

Resolution

To fix this issue, our team identified the change and rolled our application back to a previous working version. The issue was subsequently fixed prior to re-releasing it back into our product.

Remediation Items

Investigate the possibility of adding a recovery handler to our internal service.

Additional monitoring to catch similar failures if they happen again.
