At around 4:15 p.m. BST (11:15 a.m. ET), we started seeing a spike in reports for OpenAI and its ChatGPT service on DownDetector. The spike is small in the U.S., but it's over 3,000 on the U.K. version of DownDetector.
OpenAI acknowledged the outage on its status page, saying that it's seeing "increased error rates."
