How we measure this
About once an hour we read OpenAI's official status feed and record exactly what it says — we don't infer status from our own connection to them. When the feed can't be read, we record nothing rather than guess, so a gap in the chart above means “not monitored”, never “down”.
Uptime is the share of the 101 recorded checks where OpenAI was not reporting an outage — a provider flagging degraded service is still up. Providers often sit at “degraded” for days over one small component, so counting that as downtime would say a service was offline all month when its own page said nothing of the kind. Degradation is reported separately, in the figures above and the timeline below.
This is a sample, not continuous monitoring: an incident that started and finished between two checks won't appear here, and a run can be missed. Treat these figures as what OpenAI was reporting at the moments we looked — the official page is the authority. Official OpenAI status page →
