**Recent September outages and Anthropic’s track record of intermittent issues are shaping trader views on Claude downtime in October.** A major incident on September 29 caused elevated errors across claude.ai, the API, Claude Code, and Cowork for roughly two hours, following a similar event on September 22 and multiple shorter spikes earlier in the month. Official status data shows 90-day uptime of 99.4–99.8% across components, with dozens of incidents (many brief or minor) tied to scaling demands, model updates, and high-traffic features. Traders see the tight spread between 5–7 and 8–10 down days as reflecting uncertainty over whether October’s load and release cadence will produce comparable frequency, versus potential stabilization from infrastructure improvements. No major maintenance windows are announced, but ongoing model development and user growth remain key variables.
