Current ChatGPT status and full outage history
How this is measured
Readings are taken every few minutes from outside ChatGPT's network, combining their published status feed with a timed request to the service itself.
An incident opens after two consecutive bad readings and closes after two consecutive good ones, so the recorded duration may be a few minutes wider than the true outage.
ChatGPT's official status page is the authority on causes and affected components.
