1. after cluster ready, manually update the DNS for *.apps to wrong IP address.
2. check the ingresscontroller and cluster operator status
3.

1. Canary route checks for the default ingress controller are failing, but "type: Degraded" is still "False"

$ oc -n openshift-ingress-operator get ingresscontroller/default -oyaml

1. "type: Degraded" should be "True" when default ingress controller canary checks failing 
2. co/ingress should be updated to Degraded as well.

sometimes co/ingress shows degraded after changing dns, but after a while it shows available
