OpenAI’s ChatGPT service keeps experiencing issues today. After an outage took down ChatGPT for a few hours earlier today, the service is experiencing its second major outage of the day. Many users of the ChatGPT mobile apps and the web service are not seeing responses to queries right now; however, as of 1PM ET, some people say they are able to access the services again.

“ChatGPT is unavailable for some users,” says OpenAI in its status message. “We are currently investigating this issue.” The second round of issues started at around 10:30AM ET, with thousands of reports of issues showing up on Downdetector.

Around the same time that ChatGPT has had issues, users have reported problems with Google Gemini, Anthropic’s Claude AI, and Perplexity AI web search. A message in the Perplexity Discord confirmed the tool “is currently not available” as of 10:53AM ET, but there haven’t been any other updates since then.

The last major outage to hit ChatGPT came in November when the service was down for around 90 minutes, which also impacted OpenAI’s API services. The API appears to be unaffected in this latest outage. OpenAI later revealed that the November outage was related to a DDoS attack.

A Microsoft outage also took down ChatGPT search features last month, alongside the software giant’s own Copilot service.

Update, June 4th: Noted current ChatGPT status reports and reports of problems with other AI tools.
