Recent September outages, including a broad 1-2 hour disruption on September 29 affecting Claude.ai, Code, Cowork, and the API plus a shorter incident on September 22, have shaped trader views on Claude reliability heading into October. Anthropic’s status page and third-party trackers show dozens of incidents since January 2026, with elevated error rates often tied to scaling large language models under heavy demand. The close contest between 8-10 and 11-13 days reflects uncertainty over whether these infrastructure pressures will ease or persist amid competitive model releases. October begins with services operational, yet historical patterns of brief but recurring degradations across API and consumer products support expectations of multiple affected days rather than extended stability.
