Uptime counts only major and critical incidents against a provider. Degraded time is reported beside it and never subtracted, because a slow hour is not a lost hour. Overlapping incidents are counted once, days are UTC days, and every figure comes from the provider's own published status page — where the two disagree, theirs is right.

FAQ

Is Codex down today?

No. Codex is operational and has been for 4 d 3 h — last checked 8 Sep 2026 at 14:05 UTC. Codex has published no incidents today.

Is it just me, or is Codex down?

No. Codex is operational and has been for 4 d 3 h — last checked 8 Sep 2026 at 14:05 UTC. Codex has published no incidents today. If this page says operational and it is still not working for you, the problem is more likely to be local — OpenAI only publishes an incident once it has confirmed one, which is usually minutes after the first reports.

Why is Codex not working?

Codex has no incident open, so as far as its own status page is concerned nothing is wrong. That usually leaves a local cause — network, an extension, a stale session — or a fault too new to have been published yet.

How often is Codex down?

In the last 30 days Codex published 21 incident(s) and was down for 5 h 30 m, which is 99.236% uptime. Degraded time is counted separately and was 2 d 18 h.

What does this page cover?

Only the Codex components OpenAI publishes — the Codex CLI, the IDE extension and Codex in the ChatGPT apps. The rest of OpenAI's services are on its own status page, linked above.

How is uptime calculated?

Uptime counts only major and critical incidents against a provider. Degraded time is reported beside it and never subtracted, because a slow hour is not a lost hour. Overlapping incidents are counted once, days are UTC days, and every figure comes from the provider's own published status page — where the two disagree, theirs is right.

Read from Codex's own status page. Where that page and this one disagree, that one is right: this is downstream of it and can only ever be later.
