Anthropic’s Claude chatbot faced a second service disruption within 24 hours on March 3, 2026, compounding issues from the previous day. The outage impacted claude.ai, mobile apps, Claude Code, and platform services, with users worldwide reporting login failures, chat errors, and timeouts.
Thousands flagged problems on Downdetector. In the US, over 4,000 reports emerged, with roughly 70% tied to chat functions, 34% to apps, and 15% to the website. India saw hundreds of complaints, including around 500 recent ones, mainly affecting chat access.
Anthropic’s status page listed “elevated errors” starting at 03:15 UTC on March 3, noting investigations were underway with no resolution timeline. The first outage hit March 2 around 5-8 pm in several regions, also linked to high traffic; consumer services recovered after citing unprecedented demand, while APIs stayed largely operational.
The disruptions coincide with Claude topping Apple’s free app charts and a user surge, alongside Anthropic’s public rift with the Pentagon over surveillance and weapons tech limits. No root cause beyond demand has been confirmed, highlighting strains on AI infrastructure amid rapid growth.
