Elevated latency in the Responses API

What to do

• Check whether you use OpenAI Responses. 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 20h 38m it lasted.

  Anything that failed between 2026-08-31 22:27 UTC and 2026-09-01 19:05 UTC may need a replay.

• Subscribe to OpenAI's feed to hear about the next one first. RSS feed
