Claude was down for many — Anthropic says the outage is now 'resolved'

What happened

Claude was unavailable to thousands of users again on Tuesday morning. Anthropic confirmed 'elevated error rates' across models and declared the issue resolved at 12:44 ET.

Context and impact

This was the tenth significant service disruption in three weeks. Reliability is becoming a key competitive factor as companies build production agentic workflows on top of the Claude API. Repeated outages undermine Anthropic's argument that it is serious 'critical infrastructure'.
