Claude down – Anthropic’s Claude hit by fresh outage, fifth disruption in March

Anthropic’s artificial intelligence chatbot Claude faced another service disruption on March 27, marking the fifth reported outage this month.

As of 2:49 PM, nearly 120 users flagged issues with the platform on Downdetector, indicating a fresh wave of access and performance-related problems. The latest disruption follows a similar outage reported on March 25 and March 17.

Anthropic confirmed the issue and said that it is currently investigating the cause. The outage comes just weeks after a series of earlier service disruptions affecting the platform.

The disruption appears to be widespread, impacting multiple components of the AI ecosystem, including Claude Chat, developer-focused tools such as Claude Code, as well as the company’s digital assistant Claude Cowork and its most advanced model, Claude Opus 4.6.
