Claude AI experiences widespread outage on Tuesday, June 23

Anthropic's Claude artificial intelligence service experienced significant instability on Tuesday, June 23, 2026, affecting multiple platforms and services. Users reported widespread service disruptions beginning in the late morning, with the primary issue involving message loading failures across various Claude models. By 11:31 AM Brasília time, Claude's official status page indicated elevated error rates affecting multiple models, including the company's most powerful publicly available model, Claude Opus 4.8.

The outage impacted most of Anthropic's services, including Claude.ai (the main chatbot), Claude Console, Claude API, Claude Code, and Claude Cowork. The only service operating without reported errors was Claude for Government. Anthropic acknowledged the issue and stated that "the problem was identified and a correction is being implemented." By approximately 12:20 PM, the company reported it was monitoring the results of its remediation efforts. Testing by media outlets confirmed that the chatbot became accessible following the implemented fixes.

In a coincidental timing, ChatGPT, OpenAI's competing AI service, also experienced problems on the same day. The ChatGPT outage was more limited in scope, affecting file upload and download functionality while other features continued to operate normally. The simultaneous disruptions at both major AI platforms drew user attention to the infrastructure challenges facing large-scale AI services.
