"disruption_tests: [sig-network-edge] Cluster frontend ingress remain available" is failing

I am seeing "disruption_tests: [sig-network-edge] Cluster frontend ingress remain available" test fail in periodic-ci-openshift-release-master-nightly-4.9-upgrade-from-stable-4.8-e2e-aws-upgrade. This is one of the failures causing 4.9 payload releases from being accepted.

OCP 4.9
