OpenAI Codex had a full outage for about an hour across web, API, CLI and the VS Code extension

Sources: primary, discussion, discussion
Summary: The OpenAI status page records an incident on 2026-09-25 running from 10:58 PM to 11:54 PM on the page's own clock, covering Codex on the web, the API, the CLI and the VS Code extension. At 11:19 PM the page posted that login via API key would unblock access, between its 11:03 PM and 11:34 PM updates.
Why it matters: The API-key fallback is published by OpenAI on the incident page itself, so it is worth reading before the next Codex incident rather than during it.
