Summary
OpenAI said some ChatGPT and Codex users were still seeing elevated error rates after a partial outage that had lasted about four hours.
Two hours into the incident, OpenAI applied a mitigation and said it was monitoring recovery, though it had not identified the underlying cause publicly.
DownDetector reports were trending lower after earlier spikes, but users on X continued to report access problems, suggesting the disruption had not fully cleared.
The incident was listed on OpenAI’s status page as an ongoing investigation affecting both services, with no timeline yet for full resolution.
