      Patterns and Insights

      This is an existing test that has regressed significantly. The test had a 100% success rate in the base release (4.20) but has dropped to 85% in the sample release (4.21), indicating a clear regression. The failures appear to be consistent within the `periodic-ci-openshift-release-master-nightly-4.21-e2e-vsphere-ovn-techpreview` job. There were no flakes observed in either the base or sample periods, suggesting a direct failure rather than intermittent flakiness.
