Anthropic Investigates Elevated Errors on claude.ai, Claude Code and Claude Console

Anthropic is investigating elevated errors across three Claude services, with authentication issues on claude.ai and Claude Code highlighting problems accessing its AI tools.

Anthropic marked the incident under investigation at 4:58 a.m. ET (09:58 UTC) Friday, Nov. 13. It listed elevated errors on claude.ai, Claude Code and platform.claude.com (Claude Console), while specifying authentication issues on the first two.

The incident is separate from the Claude disruption Anthropic investigated Sept. 29, which included claude.ai, Claude Code and Claude Cowork. Users then could encounter failed requests, errors when loading or sending conversations, and prompts to sign in again.

The Nov. 13 public notice gave no cause or estimated restoration time. Anthropic said it would provide an update as soon as possible.
