Anthropic’s popular AI assistant Claude experienced a major service interruption this week, with users around the world reporting that the chatbot was unavailable on both mobile apps and the web.
According to outage trackers like Downdetector, recorded over 3,500 complaints with users reporting errors such as failed logins, slow responses, and complete service failures as the disruption unfolded, FirstPost reported.
The company acknowledged the problem on its official status page, stating that several parts of the service were seeing elevated error rates — particularly the web interface and login/logout systems — though the core Claude API itself was largely unaffected and still functional for developers integrating the model into other applications.
Many users shared screenshots and messages on social platforms showing timeout errors and messages like “Claude will return soon,” while reports indicated that issues were especially noticeable with chat features, the mobile app, and Claude Code tools.
Anthropic engineers identified the cause of the outage as an unprecedented surge in demand and implemented fixes to stabilize service. The company is working to strengthen infrastructure after daily sign-ups hit record levels in recent days, according to internal updates.
The surge in users comes amid a political standoff between Anthropic and the Pentagon over how its AI models may be used in military settings.
The services have been restored now.
