Description
The problem runs on social-network. Simulate a fault where DNS resolution fails for services in the social network application. CoreDNS is configured with an NXDOMAIN template for the service `user-service.social-network.svc.cluster.local`, causing DNS resolution to fail for this service. Inject the fault by disrupting DNS resolution mechanisms (CoreDNS, service DNS, etc.) for the user-service.
