The incident began at 6:58 PM and was marked resolved at 7:54 PM, a span of about 56 minutes.
The status record lists four affected components: Codex, Codex Web, the Codex API, the CLI, and the VS Code extension. OpenAI first reported elevated errors and an internal issue. At 7:19 PM it said that logging in with an API key would unblock access at that time.
OpenAI later said it had identified the root cause, applied a mitigation, and was monitoring recovery before declaring all impacted services fully recovered. The incident page links to a published write-up. The supplied status updates do not state the technical cause, the number of customers affected, or whether the API-key workaround worked for every affected user.
