- Mitigation preceded full recovery.
What changed
OpenAI's September 14 incident report says Agents API customers experienced delays or could not start turns in managed sessions from 1:30 p.m. Pacific Time. A subsequent update reported recovery after mitigation while acknowledging that service was not yet fully restored. The final update says managed sessions were processing turns normally.
Why it matters
For operators integrating the API into automated work, the distinction between accepting a session and starting its next turn matters. A delayed turn can leave a workflow waiting even if its surrounding application remains available. That is an operational implication rather than a measured customer outcome.
What remains unproven
The report gives no root cause, affected request count or account breakdown. It also leaves its affected-components field empty, limiting conclusions about the disruption's wider scope.
