The Kill Switch: How an Automated Google Cloud Error Instantly Wiped Out the Railway Platform

Railway suffered a protracted, large-scale operational blackout after Google Cloud Platform automatically terminated organizational accounts and deactivated hosted server instances—an action the report attributes to a regression in GCP’s automated anti-abuse filtering that produced platform-level false positives. Affected customers reportedly received no prior notice, Google provided only private briefings without a detailed public post-mortem or SLA compensation, and the incident highlights the availability risk of single-cloud dependency and the need for cross-cloud backups or migration.
