Incident Report
Summary AI Generated
GitLab's Duo Agent Platform and LLM proxy endpoints experienced rate limiting issues that caused errors when users attempted to access Claude models for 12.4 hours. The incident was resolved by implementing traffic filtering rules to block excessive requests, which reduced rate limit errors to near zero and restored Claude model availability. A permanent fix was deployed with continued monitoring for follow-up improvements.
We are currently investigating an issue with Duo Agent Platform and LLM proxy endpoints hitting rate limits. Users may experience errors using Claude models. We recommend switching to a different model as a workaround.
