**Claude's service reliability underpins the market's strong lean toward minimal downtime.** Official status data through November 10 shows all components operational, with 90-day uptime averaging 99.7–99.86% across claude.ai, the API, and related platforms. The only November incident so far—a 26-minute degraded performance event on November 8 for the Fable 5.1 model—fits the pattern of brief, resolved issues rather than extended outages. Recent months reinforce this track record: October saw roughly a dozen short incidents (mostly 30–240 minutes of elevated errors or degraded performance on connectors and models), while September incidents were similarly contained. No full-day outages have been reported in November, and Anthropic continues to demonstrate rapid mitigation through infrastructure on AWS and other platforms. Traders price the <5 days bucket highest because cumulative downtime has historically remained low even during active development cycles. The 5–7 day range captures modest room for additional minor events, while probabilities above 8 days stay thin given the absence of systemic risks or major scaling disruptions. Upcoming model releases or connector updates could introduce short-lived volatility, but the current operational baseline favors limited total impact for the month.
