WalkthroughThe change adds a DNS disruption statistics monitor, registers it by default, and adds legacy network monitor coverage. The legacy check fails when DNS disruption events exceed 50. ChangesDNS disruption monitoring
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to This change adds DNS disruption statistics and threshold coverage, with no identified correctness or operational risk remaining; it is ready to merge after normal checks. Caution Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional.

Full details: Stable And Deterministic Test NamesExplanation The new subtest titles are static across runs, and no title contains a pod, node, namespace, timestamp, IP, or generated identifier. However, Full details: Test Structure And QualityExplanation The added table test is otherwise focused and does not create cluster resources or perform waits, so setup, cleanup, and timeout requirements do not apply. However, the new assertion Resolution Add a meaningful message to the result-count assertion, such as

We need a more crisp detection mechanism for job runs hitting serious mass disruption. Existing test flakes if we see ANY, that's quite common, but these runs where we have catastrophic outages are difficult to hunt for. This test should make it easy to find job runs across platforms and build clusters.
