Anthropic restores Claude access after brief outage affecting users globally

Anthropic’s AI chatbot platform, Claude, experienced a brief outage on Thursday, June 18, disrupting access for many users across several regions. The downtime was first detected by outage tracking service Downdetector, which recorded over 2,174 user reports at the peak of the incident. Affected users reported blank replies, failed prompts, and connection errors.

Anthropic acknowledged the issue at 7:41 AM UTC (1:11 PM IST) on the official Claude status page, stating, “We have identified the cause of the issue affecting Claude.ai and are working on a fix.” The company later confirmed that the problem was resolved as of 8:19 AM UTC (1:49 PM IST), with impact lasting from 06:55 to 07:40 UTC.

The outage adds to a series of service disruptions in June, including elevated error rates for Claude Opus 4.8 and Claude Haiku 4.5, as well as performance issues affecting both the chatbot and its API services. Anthropic has attributed these challenges to rapidly growing demand for its AI products, including Claude Code and other enterprise tools, which has put pressure on its compute infrastructure.

The company is working to expand capacity through partnerships with major cloud providers, though some additional resources are not yet fully available. Anthropic continues to monitor the situation and advises users to check its official status page for updates.
