Intermittent 500s on Inference Endpoint - requests not reaching the container

A user reports intermittent HTTP 500 errors on a custom-handler Inference Endpoint for text embeddings, with ~70% of requests failing since early morning on 2026-07-14. The failures appear to occur at the gateway/router layer before reaching the container, as container logs only show successful requests. The user has ruled out GPU-specific, endpoint-specific, and code-related issues, and seeks information about a possible known problem with the us-east-1 inference gateway.

I’m using a personal account. I’m running a custom-handler Inference Endpoint for text embeddings Llama-3.1-8B . Since early this morning on 2026-07-14, I’m getting intermittent HTTP 500s ~70% of requests fail, ~30% return 200 normally . What I’ve ruled out: Not GPU-specific - happens on both L40S and A100. Not endpoint-specific - brand-new endpoints show the same. Not my code/deps - the same build ran hundreds of thousands of requests fine yesterday. Container is healthy - model loads successfully, and successful requests return correct results in 30–415 ms. Key finding: the container logs only show the successful requests. The failed 500 requests don’t appear in the container logs at all — they seem to be failing at the gateway/router layer before reaching the container. The status page shows no incident. Is there a known issue with the us-east-1 inference gateway, or something on my account causing this? Happy to share endpoint IDs privately. Thanks
