Elevated latency for some API requests

What to do

• Check whether you use OpenAI Responses, Chat Completions. Check your stack

  Paste a package.json, lockfile, Terraform or a list of domains at down.guide/stack to see every provider you depend on.

• Confirm your retries, queues and scheduled jobs caught up after the 3h 30m it lasted.

  Anything that failed between 2026-09-30 17:05 UTC and 2026-09-30 20:35 UTC may need a replay.
