Anthropic has confirmed and resolved a significant service disruption that impacted its flagship AI chatbot, Claude, on Wednesday, April 15. The outage disrupted several key platforms, including the web interface, the API, and specialized tools like Claude Code.
The Scope of the Disruption
The incident caused widespread accessibility issues for users attempting to interact with Anthropic’s ecosystem. According to the company’s official status monitor, the disruption was characterized by two distinct phases:
– A major outage lasting 40 minutes.
– A partial outage lasting an additional 73 minutes.
The technical difficulties were not limited to a single interface. Users reported failures across Claude.ai, Claude Code, and the Claude API. Some users experienced login failures, while others encountered error messages claiming they had reached message limits, even when no messages had been sent.
User Impact and Error Trends
Data from monitoring services indicated a sharp spike in user reports around 10:30 a.m. ET. The frustration was distributed across various ways users interact with the AI:
– 38% of reported issues concerned the Claude Chat interface.
– 29% were related to Claude Code.
– 25% involved the Claude App.
While some users encountered “service busy” pop-ups—which can sometimes be mistaken for a total system failure—the scale of reports confirmed a genuine infrastructure issue.
Context: The Pressure of Rapid Growth
This outage occurs during a period of unprecedented scaling for Anthropic. The company has seen massive user acquisition recently; reports indicate that Anthropic has been gaining over 1 million new users per day.
This rapid expansion places immense pressure on cloud infrastructure and API stability. As AI companies race to accommodate millions of new daily users, the “growing pains” of service outages become a recurring challenge for the industry. Maintaining high uptime becomes increasingly difficult as the sheer volume of concurrent requests scales alongside the user base.
Current Status
Anthropic has officially marked the incident as resolved. A company spokesperson expressed appreciation for user patience during the restoration process. Despite the disruption, Anthropic’s 90-day uptime remains high, sitting at approximately 98.79%.
Summary: After a period of significant instability affecting multiple Claude platforms, Anthropic has successfully restored all services and is working to manage the demands of its rapidly expanding user base.
