Railway experienced a platform-wide service disruption due to a Google Cloud Platform (GCP) account suspension, resulting in a temporary loss of service for all GCP hosted infrastructure. The suspension was caused by an automated action that flagged Railway's account as a violation of GCP's Terms of Service. Railway worked with Google Cloud to recover from the incident and is now taking steps to prevent similar issues in the future. The incident highlighted the risks of building on top of someone else's platform and the importance of having a resilient architecture.
