If you encountered an issue asking ChatGPT for a morning update, a topical question, or wanted to give the new Agent mode a try, you weren't alone as OpenAI confirmed a partial outage lasted for a little over an hour on July 21, 2025.
At it's peak, we tracked over 1,500 reports in the US and nearly 1,000 reports in the UK on Down Detector – a site that tracks issues with platforms – and OpenAI’s own status page confirmed ChatGPT was in the midst of an outage for paid subscribers.
