Trader consensus on the 1-3 hour range for GitHub's longest critical incident in September stems primarily from the platform's rapid incident response patterns, with a median resolution time of roughly 80 minutes across dozens of events and no prolonged outages qualifying as critical in official postmortems. Key September 2026 incidents, including the September 13 multi-service degradation from a database cleanup job and the September 28 Copilot Code Review outage, were contained within 1-2 hours through load shedding, rollbacks, and targeted fixes. The September 23-24 database failover event saw core API errors mitigated in under three hours despite extended backlog processing. Realistic challenges to this positioning include reclassification of a multi-day billing or Projects backlog issue as critical, or an undetected gray failure extending beyond historical norms.
