ChatGPT was down for many users again today, with a significant number experiencing slow performance and error messages – in a more minor repeat of the problems we saw on March 31.

The website Downdetector again showed a large spike in reports in the US and UK at around 9am ET / 2pm BST, which was the same time we saw issues on Monday.

Previously, users reported either laggy performance or error messages like "something went wrong" on the desktop version and "upstream connect error" on the mobile app. Today, the OpenAI status page acknowledged a combination of "login issues" and "increased error rates".

Alongside OpenAI's status page messages, OpenAI CEO Sam Altman has also now responded on X (formerly Twitter), stating that "we are getting things under control, but you should expect new releases from openai to be delayed, stuff to break, and for service to sometimes be slow as we deal with capacity challenges".

The number of ChatGPT users reporting issues has now dropped significantly, but issues continue to rumble on as OpenAI works on "implementing a mitigation". Here's everything we know about ChatGPT's week of outages...


The latest news

  • ChatGPT has again experienced issues with error messages and log-ins
  • The problems started at around 9am ET / 2pm BST today
  • OpenAI CEO Sam Altman says the company has "capacity challenges"

Refresh

OpenAI CEO Sam Altman responds

We now have our first comment about ChatGPT's patchy performance this week from OpenAI CEO Sam Altman (above). His post on X (formerly Twitter) confirms what most of us have been thinking – that the problems are related to the company's frantic rollout of major features like ChatGPT's new image generator.

Yesterday Altman was crowing that ChatGPT had acquired "one million users in the last hour". To put that in perspective, ChatGPT took five days to attract the same number of users when it launched in 2022 – when it became the fastest-growing consumer app in history.

So yes, we can see why OpenAI might be experiencing capacity issues, while also having lots of sympathy for the paying ChatGPT Plus users who are wondering why on earth the company just rolled out the new image generation feature to free users – and is now apparently considering doing the same with Deep Research.

'One step at a time' clearly isn't really a phrase in OpenAI's lexicon, for better and worse...

Looks like ChatGPT had two issues

OpenAI posted on its Status Monitor that its login issues were resolved at 9.20am ET / 2.20pm BST, so why have lots of users been having problems since? It turns out a second issue, our old friend "increased error rates" from yesterday, has also returned over the past few hours.

That might explain why ChatGPT has been uncooperative for you again today. Fortunately, at 11.12am ET / 4.12PM BST, OpenAI posted that "all impact services have now fully recovered", so we should see those error messages fizzle out, leaving us to melt OpenAI's GPUs again in peace.

The ChatGPT problems return...

At almost exactly the same time as yesterday (9am ET / 2pm BST), there's been another spike in reports of ChatGPT problems on Downdetector – and OpenAI has also confirmed "login issues" on its Status page.

At the time of writing, there have been almost 1,500 reports from frustrated ChatGPT users in the US on Downdetector, though the spike in the UK has almost completely reversed.

The good news is that the 'history' section of OpenAI's status page posted at 9.20am ET / 2.20am BST that "all impacted services have now fully recovered" and that "users globally should be able to login without issue". So hopefully this tremor should be short-lived and a bit less disruptive than yesterday's...

ChatGPT is back to its old self

Aside from an ongoing wrinkle around new signups for ChatGPT and Sora in some regions, the AI chatbot now seems to have recovered from its latest wobble – and is back to full working order.

That's good, because its Monday 'to do' list contains around two billion requests for Studio Ghibli-style images and more, so it had better get cracking.

We'll be keeping a close eye on ChatGPT this week, because it's clearly been under strain from some unpredented load following the roll-out of its viral image generation feature. But for now, we're happy to see that it's back to its error message-free self.

A promising sign...

OpenAI has now removed the message acknowledging "increased error rates" on ChatGPT from its status page – which suggests the problems are now easing.

That's also reflected in the Downdetector graph above too, which shows that only around 120 people reported problems with OpenAI in the US at the time of writing (and that number is fortunately even lower in the UK).

This means today's issues likely won't be a repeat of the big outage in January 2025, which saw over 10,000 people report problems at a peak that was caused by a widespread "bad gateway error". Good news – you may recommence your Ghibli-themed image generation, unless you're too much of a fan to do it...

OpenAI may be rolling out a fix...

Some potential good news for those who are struggling to get ChatGPT to make images of monkeys riding Segways (or help with more serious work) – the OpenAI Status page now says "we are working on implementing a mitigation".

Yes, that statement is so non-committal is must have been written by ChatGPT, but it at least promises that the AI chatbot will be running a bit more smoothly soon. The spike in Downdetector reports have also dropped significantly, so perhaps it's already working for some...

Is "biblical" demand to blame?

While OpenAI hasn't officially commented on what's causing today's ChatGPT problems, it's hard to escape the conclusion that the soaring demand for its new image generator has at least had at least some impact.

Sam Altman has been posting increasingly concerned messages to X (formerly Twitter) over the past few days, starting by stating that "our GPUs are melting" from the Ghibli craze on March 28 to a "this is insane our team needs to sleep" yesterday on March 30.

In a reply, Altman added that OpenAI hadn't been able to catch up with the increased load, adding "biblical demand, I have never seen anything like it". Well, perhaps OpenAI should have thought of that when it stoked the Ghibli fire.

In our tests, we've found that ChatGPT's image generator is still working, but is very slow going – much like the rest of the AI chatbot today...

Is Gemini having issues too?

Maybe we do need more of those AI chips and GPUs after all – it seems Google Gemini also experienced a minor outage at the same time as ChatGPT, though its issues seems to be largely resolved already.

We noticed error messages like the above in Gemini recently and Downdetector showed a fairly big spike in reported problems at around 9.36am ET / 2.36pm BST. This could point to DNS issues affecting both Gemini or ChatGPT, or it may be unrelated.

Either way, Gemini seems to be back to its old self – while OpenAI is seemingly having a second spike in reported problems, according to Downdetector...

OpenAI acknowledges ChatGPT issue

So it wasn't just our collective imaginations – OpenAI's Status page is now showing an "Increased Error Rates" issue for ChatGPT.

The notice states that "we are investigating the issue" but doesn't provide any more information about a cause, other than it's been "ongoing for 2hr".

The description seems to fit our experience – while it isn't a complete outage for the service, we have certainly been seeing a lot or error messages.

The Downdetector reports seemed to have dropped slightly from their earlier peak, but not by far – with the number hovering at around the 1,000 mark at the timing of writing. Seems like ChatGPT had a heavy weekend on the old Ghibli cocktails...

You may be seeing this a lot today...

It isn't yet clear what's causing today's ChatGPT problems, but OpenAI's status page says it's investigating a live incident.

The problems seem to be intermittent and producing a variety of lovely symptoms, including the "something went wrong" message above and the classic "upstream connect error" (always a favorite) on the mobile app.

While it's a bit too soon to blame the Studio Ghibli image craze, it's hard to ignore the timing of Sam Altman's increasingly panicked X posts telling us to stop making so many...

When did the problems start?

According to Downdetector, the latest ChatGPT outage started at around 9am ET / 2pm BST, when we saw a big spike in reports in both the US and UK.

The issues are seemingly intermittent, with the main problems including "something went wrong" error messages in ChatGPT's browser version and "upstream connect errors" in the mobile app.

We've seen both issues on the TechRadar team, though it doesn't appear to be a complete outage that's affecting everyone equally...
