Unable to initiate or continue new or existing chats ChatGPT App. Complete service outage #35315

Description

@gkjpettet

What version of the Codex App are you using (From “About Codex” dialog)?

26.721.41059

What subscription do you have?

Max ($100/month)

What platform is your computer?

Darwin 25.5.0 arm64 arm

What issue are you seeing?

Description

Got a 503 with auth error code: biscuit_baker_service_me_circuit_open immediately after quitting and reopening Codex, on a basic/simple question. I have plenty of usage remaining and am on the Max plan, so this doesn't appear to be a quota or rate-limit issue.

Error output

unexpected status 503 Service Unavailable: Service Unavailable, url: https://chatgpt.com/backend-api/codex/responses, cf-ray: a209fbb14b0c4af5-LHR, auth error: 503, auth error code: biscuit_baker_service_me_circuit_open ​

What steps can reproduce the bug?

  1. Ask a basic/simple question in the ChatGPT app
  2. Request fails immediately with the above 503

What is the expected behavior?

The model should answer.

Additional information

Shortly before this, I also got a separate 503 ("error":"Too many concurrent requests", "code":"throttled", "source":"concurrency_limit") on the same account — noting in case they're related, though they look like distinct failure modes (client-side throttle vs. server-side circuit breaker).

At the time, https://status.openai.com showed no active incident, though there have been other reports of biscuit_baker_service_me_circuit_open tied to a partial outage.
