Elevated timeouts on LiveKit Inference (google/gemma-4-31b-it)

We are monitoring elevated timeouts that affected LiveKit Inference between 14:05 and approximately 15:00 UTC today. During that window, roughly 3% of LLM requests using the google/gemma-4-31b-it model timed out. Impacted customers would have seen LLM request timeouts in their agent sessions (for example, APITimeoutError in agent logs). Other models were not affected. We have identified the cause. During a period of increased traffic, response times for this model slowed, and a defect in our health-monitoring logic incorrectly marked a backup deployment as unhealthy and removed it from rotation, preventing requests from failing over as designed. Error rates returned to baseline by approximately 15:00 UTC, and a fix for the health-monitoring defect is in progress. We are continuing to monitor before marking this resolved. No action is needed on your part. If you continue to see timeouts, please reach out to support. We apologize for the disruption.
