On a typical morning in the UK, users of Claude AI began to notice significant disruptions in service. Reports started surfacing that the AI tool, developed by Anthropic, was not functioning properly, leading to widespread confusion and frustration among its user base.
By mid-morning, Down Detector confirmed that users were experiencing problems, although it was noted that this was not a full outage. Initial reports indicated that more than 5,000 users were facing issues, with complaints peaking at over 6,800 per hour.
As the day progressed, the problems persisted, with 44% of users specifically reporting issues with chat functionality. The outage has been commonly associated with API Error 500, which signifies an internal server error, indicating deeper issues within the system.
The outage has affected both the Opus and Sonnet systems that power Claude’s responses, disrupting chat services and access to essential development tools for thousands of users globally. This has raised concerns about the reliability of AI tools that many depend on for coding, research, and productivity.
Jenesh Napit, a user affected by the outage, remarked, “Claude Code is down, basically a snow day,” highlighting the impact of the disruption on daily workflows.
As of now, ongoing reports indicate that around 1,000 users are still experiencing issues, suggesting that the situation is far from resolved. Users continue to seek clarity on when services will return to normal.
Details remain unconfirmed regarding the exact cause of the outage, leaving many users in the dark about the nature of the problem. The dependency on AI tools like Claude underscores the importance of reliable service in today’s tech-driven environment.
As the situation develops, users are encouraged to stay updated through official channels from Anthropic for any announcements regarding the restoration of services.
