From 07:08 to 07:43 UTC on October 8, 2026, the LLM Gateway (gateway.smith.langchain.com) returned high 502 error rates. It was due to an incorrect infrastructure configuration change that stopped traffic from reaching the gateway.
We fully restored the service at 07:43 UTC, and no other LangSmith services were affected. We're sorry for the disruption.
