Final update

On May 28, 2026, between 00:54 UTC and 01:19 UTC, some users experienced errors when interacting with the Webhooks API, including webhook delivery history and configuration endpoints. On average, the error rate was 0.28% and peaked at 0.45%. This was due to a bug that caused a single Kubernetes pod to enter a CrashLoopBackOff after receiving a 500 with an empty response body from Cosmos DB. We mitigated the incident by restarting the service. To prevent future incidents, we are pushing a change to handle this response scenario from Cosmos DB appropriately.
