Anthropic experienced significant service interruptions on Monday morning, with thousands of users reporting difficulties accessing its Claude AI services.
The widespread outage primarily impacted Claude.ai and Claude Code, though Anthropic confirmed that its Claude API remained operational. The majority of users encountered errors specifically when attempting to log into their accounts.
“The issues we are seeing are related to Claude.ai and with the login/logout paths,” Anthropic stated on its official status page. While the company has not yet disclosed the root cause of the disruption, it has identified the underlying problem and is actively working on implementing a solution.
This service disruption occurs amidst a notable surge in Claude's user base, a growth trajectory seemingly boosted by public interest surrounding Anthropic's sensitive negotiations with the Pentagon. Over the past weekend, the Claude chatbot application impressively climbed to the top of the App Store charts, surpassing its primary competitor, ChatGPT, after an extended period outside the top 20.
Adding to the company's recent spotlight, U.S. President Donald Trump last week instructed federal agencies to cease using Anthropic products. This directive followed a disagreement concerning safeguards designed to prevent the Department of Defense from deploying Anthropic's AI models for mass domestic surveillance or the development of fully autonomous weapons. Secretary of Defense Pete Hegseth subsequently indicated an intention to classify Anthropic as a supply-chain threat, although the company maintains it has not yet received any official notifications regarding such a designation.
