Outage climbs to nearly 3,000 reports within the hour

In just a span of an hour, there have been nearly 3,000 reports on Downdetector about disruptions with Anthropic’s Claude AI. Users report that the service is inaccessible. However, there’s no exact culprit to what kicked off this latest outage.

Claude says fix is in the works

The official Claude status page is already claiming that Anthropic is seeing success with an implemented fix.

This likely won’t last much longer.

Reports nose dive

After implementing a fix, reports on Down Detector took a steep nose dive almost immediately.

As of this posting reports sit around 350 on DD after a high of 3,000 earlier today.

All systems operational

Claude says all systems are operational on the official status page.

Calling it

With things green and reports under 300, we’re calling this outage as another short-lived interruption that plagues Claude several times a week.
