Description
The problem runs on social-network. Simulate a fault where CoreDNS configuration becomes stale in the social network application. CoreDNS is configured with a stale NXDOMAIN template for all .svc.cluster.local domains, causing DNS resolution to fail for all cluster-internal services. Inject the fault by preventing CoreDNS from updating its configuration or by introducing stale DNS records.
