ChatGPT is down

ChatGPT stopped working for many users on Thursday afternoon, when the chatbot suddenly couldn’t respond to queries, with some users seeing an “internal server error” message.

It looks like the outage started around 1:30PM ET, which is when reports began to spike on Down Detector. At 2PM ET, OpenAI posted an update to its status page, saying ChatGPT, the API, and its text-to-video generator Sora are “currently experiencing high error rates.” OpenAI said Sora came back online at 6:15PM ET, before seeing a “full recovery” for ChatGPT at around 11PM ET.

OpenAI didn’t specify the “upstream provider” linked to the issue, but its exclusive cloud provider, Microsoft, reported a “power issue” at one of its datacenters that started around the same time as the OpenAI problems and affected North America, and problems with Xbox cloud gaming.

Just after 5PM ET, Microsoft said it had “fully restored” power to the affected datacenter.

ChatGPT has gone down a few times in the past several months. Just days after OpenAI released Sora to ChatGPT subscribers earlier this month, the video generation tool and ChatGPT went down for hours. Meanwhile, a widespread outage affecting AI tools brought down ChatGPT in June.
