OpenAI's ChatGPT has suffered a "major outage," leaving customers unable to converse with the company's chatbot.

Problems began around 07:00 UTC on June 4, and by 07:21 UTC the company admitted that something was amiss and it was investigating. Just over an hour later, OpenAI reckoned it had worked out what was wrong and was "mitigating." As of 10.00 UTC, it told users it was "continuing to work on a fix for this issue."

The issue, according to affected users, is that ChatGPT is not responding to queries from either the mobile application or the website, indicating that the problem is likely somewhere on the server side. Indeed, when we asked the chatbot to self-diagnose, it responded with a terse "Internal Server Error."

Social media was its usual supportive self. One user complained of repeated outages and crashes, saying: "This is becoming extremely annoying and unworkable."

Another commented: "Some juniors sweating rn as openai is down and they can't fake it anymore."

And for the developers out there who have come to use suggestions from the chatbot in their coding? One remarked: "who took down openai i have code that needs to be written."

Roman Khavronenko, co-founder of monitoring outfit VictoriaMetrics, asked: "Why are sites still failing to scale up and down effectively when we were told rapid digital transformation happened three years ago?"

"Going viral isn't unusual anymore, but sites being able to handle viral traffic is still too rare. When sites crash it costs businesses more money than if they properly invested in the scalability and observability of their infrastructure. If data is the lifeblood of modern businesses, why is it still not being properly managed?"

ChatGPT has indeed been a little unreliable over the recent months, although the blame cannot be left entirely at OpenAI's door. On May 23, for example, ChatGPT lost the ability to perform web searches as Microsoft's Bing search engine suffered an outage of its own.

We asked Microsoft's Copilot about the status of ChatGPT, but it replied that it had no real-time information on the service and directed us to OpenAI's status page. On the subject of how to build a robust web service, Copilot was more forthcoming, with useful pointers on design, technology stack selection, and validation.

We would have asked ChatGPT the same question, but that pesky server error persisted.

The Register has darkened the door of OpenAI for more information on the issue, and will update this piece should the company respond. ®
