장애 보고서: 2026년 5월 19일 – GCP 계정 중단

Railway's 8-hour outage demonstrates that multi-cloud architecture is vulnerable to cascading failures when a single provider's internal systems become a critical dependency. Even though AWS and Railway Metal workloads remained operational, the edge proxies' reliance on Google Cloud's control plane API rendered the entire platform unreachable. This incident emphasizes that true resilience requires decoupling mission-critical infrastructure functions from any single provider's services.
