Supabase experienced a 3 hour 42 minute outage in us-east-2 on February 12, 2026, caused by accidentally enabling AWS VPC Block Public Access during a monitoring service deployment. The regional-level misconfiguration blocked all internet gateway traffic across every VPC. Resolution was delayed by misleading symptoms, insufficient pre-production environment parity, and missing infrastructure team representation. Supabase is implementing account isolation, external connectivity probes, deployment guardrails via SCPs, and improved incident communication to prevent recurrence.
