Recent outages, including a major September 29 incident with elevated errors across claude.ai, the Claude API, Code, and Cowork lasting over two hours, plus a prior September 22 event, highlight ongoing infrastructure strain on Anthropic's large language models amid rapid scaling and high demand. These align with similar disruptions at rival OpenAI, underscoring shared challenges in maintaining uptime for advanced AI services. Traders see moderate October downtime as likely given historical patterns of weekly incidents and 98-99% uptime benchmarks, though Anthropic's swift mitigations differentiate it from more prolonged failures; key swing factors include model release impacts and cloud capacity expansions.
