It's going to be a tough day to do anything online.

Following a massive outage affecting multiple Microsoft services that still hasn't been resolved, Anthropic's AI assistant Claude is now exhibiting issues of its own.

"We are investigating an issue with users authenticating to Claude.ai and Claude Code. We will provide an update as soon as possible," wrote Anthropic on the company's official Claude Status page.

At Mashable, we're logging into Claude fine, but we've seen reports on X that some users are having trouble logging in.

It's unclear whether Anthropic's problems are related to Microsoft's troubles.

This is a developing story. We'll update this article when we know more.
