OpenAI reports restoration of ChatGPT, Codex and API services after increased error rates

independently confirmed updated September 29, 2026

OpenAI has marked the incident of increased error rates affecting ChatGPT, Codex and API including Agents API as resolved. According to the company, all affected services have resumed operation. A root cause analysis is to be published within five business days.

OpenAI has marked the incident as resolved on its status page. According to the company, all affected services — ChatGPT, Codex and API including Agents API — have resumed operation, and the listed components now show the status Operational. The current announcement thus changes the earlier information about an ongoing outage.

An article on Lupa.cz described the inability to log in to the web interface, an unresponsive mobile app, and problems accessing the service via API. According to Downdetector, the problems were global in scope. The cause is not stated in the sources; OpenAI has promised to publish a detailed root cause analysis within five business days of the announcement.

What changed

Why it matters

According to the company, the restoration of operation allows work with the affected services to continue and processes dependent on the API to resume. The promised analysis will be essential for assessing the cause of the failure and the risk of recurrence.
