https://testgrid.k8s.io/redhat-openshift-ocp-release-4.6-informing#release-openshift-origin-installer-e2e-azure-upgrade-4.6 shows a steep drop in pass rate for `[sig-api-machinery] Kubernetes APIs remain available` happening about 9/30.
We went from passing 72% of the time to passing 56% of the time. There is also a drop in 4.5 to 4.6 upgrades from 71% pass to 66% pass.
There is a clear change in behavior. Something regressed in our last 7-10 days, around 9/30ish.
https://bugzilla.redhat.com/show_bug.cgi?id=1882750 started failing a lot more often on azure at nearly exactly the same time.
In last 11 runs we only have 2 fails. That's 82% pass-rate.
I'm seeing flakes rather than failures, waiting to see the impact of pending fixes on that flake rate.
I’m adding UpcomingSprint, because I was occupied by fixing bugs with higher priority/severity, developing new features with higher priority, or developing new features to improve stability at a macro level. I will revisit this bug next sprint.
test-grid broke when this was written. test grid has since been fixed.
