Anthropic faced significant disruptions on Monday morning, with numerous users reporting difficulties accessing Claude services.

The outage appears to impact both Claude.ai and Claude Code, although the company stated that the Claude API is functioning as expected. Most users encounter the error while trying to log in, as depicted in the screenshot below.

“The problems we are experiencing pertain to Claude.ai and the login/logout processes,” the company’s status page indicates. Anthropic has not provided specific details regarding the cause of the outage, though they have acknowledged an issue and are working on a solution.

The disruption comes after a surge of users to Claude, which seems to have gained from the attention surrounding the company’s tense negotiations with the Pentagon. The chatbot app climbed to the top of the App Store rankings this weekend, surpassing competitor ChatGPT, after a prolonged period positioned outside the top 20.

U.S. President Donald Trump instructed federal agencies last week to cease using Anthropic products following a disagreement over safeguards that prevent the Department of Defense from utilizing its AI models for extensive domestic surveillance or fully autonomous weaponry. Secretary of Defense Pete Hegseth stated he would classify the company as a supply-chain risk, although Anthropic reports that it has not yet received any official notifications.
