On April 15, 2026, users of Anthropic’s Claude AI chatbot encountered a major service disruption. Both free and Pro accounts reported login failures, verification-code glitches, and “service is temporarily busy” errors that prevented prompt submissions. The company’s status page confirmed the outage, while third‑party monitors lagged behind. By late afternoon, login rates began to stabilize and Pro users regained limited functionality, but many free users still faced errors. Anthropic has pledged further updates as it works to fully restore the platform.
Anthropic’s Claude AI platform suffered a significant outage on April 15, 2026, leaving thousands of users unable to log in or submit prompts. The issue first surfaced on the company’s status page, which listed a blanket failure for Claude.ai and the Claude Code login pathway. Users on both mobile and desktop reported the same error messages, regardless of account type.
Free‑tier users saw the platform claim they had exhausted their daily prompt allotment, even though they had not issued a single request. Pro subscribers faced a different hurdle: verification codes sent by email never reached the login screen, effectively locking them out of the service. The error "Service is temporarily busy" appeared across the board, halting any attempt to generate a response.
Downdetector, a user‑reporting tool, initially suggested a rapid recovery, but its data lagged behind the on‑the‑ground reality. Anthropic’s own status updates, posted at 12:30 PM ET, indicated that login success rates were stabilizing and that engineers were working toward a full resolution. By early evening, some Pro users, including a tester named Lance, managed to sign back in on desktop, though prompts still returned the generic busy message.
The disruption manifested differently across devices. The Claude iOS app remained completely inaccessible, while the desktop web interface allowed login but failed to process any input. Users noted inconsistent messaging, such as the platform erroneously reporting daily limit exhaustion and offering upgrade prompts to the paid plan.
Anthropic’s communications have been sparse, offering no definitive timeline for a complete fix. In the meantime, affected users turned to alternative AI chatbots like Google Gemini and OpenAI’s ChatGPT, both of which appeared operational. The company’s next status update is expected to clarify whether the remaining errors stem from model availability or backend capacity constraints.
Industry observers see the incident as a reminder of the fragility of AI‑driven newsrooms and content‑generation platforms that rely on continuous uptime. As AI news tools become integral to newsroom workflows, outages can ripple through editorial calendars and automated publishing pipelines.
Anthropic has asked users to report their experiences and participate in a poll to gauge the outage’s impact. The company assures that it will provide further details as the situation evolves.
