Claude is down for many — here's what we know about the outage

The popular AI assistant Claude has gone down for many today, with Anthropic confirming that it's working on fixing the issue.

The problems started at around 2.10am ET / 7.10am GMT, when a spike in reports appeared on Downdetector. At the time of writing, those reports are still climbing and have hit 216 reports in the UK. There are also currently 139 reports in the US.

The Claude Status page has confirmed a "partial outage", but says "a fix is being implemented". Here's the latest news on Claude's issues today...

'Still working on it...'

Today's Claude issues don't seem to be restricted to its Opus 4.6 model, despite Anthropic's latest update (see below).

When I try to use Sonnet 4.6, for example, it simply hangs indefinitely with "gathering my thoughts" and "still working on it" messages. Others are also reporting that the chatbot is very slow for them this morning, although Downdetector reports are moving in the right direction...

An update from Anthropic

The Claude Status page has just posted an update suggesting this isn't going to be a quick fix.

It now reports "elevated errors on Opus 4.6", which is Claude's latest flagship model announced in February. The update adds that "we are continuing to work on a fix for this issue".

Considering it's now been three hours since Anthropic said a fix was being implemented, it seems this may be proving tricky to solve....

A slow start to the day

Reports of issues on Claude have been steadily climbing on Downdetector over the past 90 minutes in the UK. Most people are having issues with Claude Chat, with other services like Claude Cowork and Claude for Government seemingly unaffected.

However, there are signs that reports are dropping slightly, which could be related to the fix that Anthropic says is "being implemented".
