Claude outage reports surged Monday morning as thousands of users said they were unable to access Anthropic’s AI services.

The disruption appears to be affecting both Claude.ai and Claude Code, according to the company’s status page. Anthropic said its Claude API remains operational, but users attempting to log in or log out have encountered persistent errors.

Claude Outage Triggers Claude.ai Login Error Down Reports

Anthropic acknowledged the problem publicly, noting that “the issues we are seeing are related to Claude.ai and with the login/logout paths,” according to its status page.

For many users, the issue presents as a Claude.ai login error down scenario, preventing them from accessing the chatbot interface altogether. Screenshots shared online show failed authentication attempts during sign-in.

The company said it has identified the issue and is implementing a fix, though it has not disclosed the underlying cause of the disruption.

While the Claude API is reportedly functioning as intended, the login-related breakdown has effectively locked out a large segment of users who rely on the web interface and related services.

Claude App Store Surge Traffic Overload Follows Political Spotlight

The Claude outage comes on the heels of a notable spike in popularity for Anthropic’s chatbot app.

Over the weekend, Claude rose to the top of the App Store charts, surpassing rival ChatGPT after spending an extended period outside the top 20. The timing coincided with increased public attention surrounding Anthropic’s negotiations with the Pentagon.

Last week, U.S. President Donald Trump told federal agencies to stop using Anthropic products following a dispute over safeguards designed to prevent the Department of Defense from deploying the company’s AI models for mass domestic surveillance or fully autonomous weapons.

Secretary of Defense Pete Hegseth said he would designate Anthropic as a supply-chain threat. However, the company has stated it has not received any formal notice regarding such action.

While Anthropic has not directly linked the Claude App Store surge traffic overload to the outage, the timing suggests the platform may have experienced elevated user demand.

For now, the company says it is working to restore full functionality. As users wait for resolution, the Claude outage highlights how quickly infrastructure strain can follow a surge in attention — especially when AI platforms find themselves at the center of political and public debate.
