April 2026: Contentstack - AWS EU - Full outage
Contentstack experienced a full outage in the AWS EU region lasting 1.3 hours, affecting all services including Content Delivery API, Content Management API, Web Application, and other core components. The issue was caused by a problem with the ingress controller during an AWS EKS Kubernetes cluster upgrade, which disrupted traffic routing across the region. The engineering team identified the root cause, implemented a fix to restore traffic routing, and resolved the incident after monitoring for stability.
