On Tuesday, June 23, Anthropic's Claude platform experienced a major outage, with Downdetector reports surging past 8,000 in the United States alone. The disruption began at approximately 10:02 a.m. ET, with reports climbing past 7,000 within the first hour. Anthropic's status page confirmed a "major outage" affecting the claude.ai chat interface, the developer API, Claude Code, and the Claude Cowork desktop tool simultaneously; Claude for Government was the only component listed as unaffected. By 10:53 a.m. ET, Anthropic posted that a fix had been implemented. This outage arrived after a documented run of service failures across June, including a widespread outage on June 2 traced to a critical bug causing Claude Code's sub-agent system to multiply exponentially and run in an infinite loop. According to Downdetector data from that incident, 60 percent of user complaints centered on Claude Chat, 24 percent on the mobile app, and 8 percent on Claude Code. A separate major outage on June 5 hit the same services, during which an AI researcher publicly alleged that Claude's API was returning responses meant for other users; Anthropic investigated and found no evidence of a customer data breach.
