How to Investigate Kubernetes Services That Route Traffic to Old Pods

Traffic may reach old replicas due to endpoint readiness, selector overlap, connection pooling, or incomplete rollout cleanup.

Checks to make

Inspect service selectors and EndpointSlices, compare pod labels and readiness, review rollout status, and check client keepalive behavior. Confirm old pods have terminated and observe traffic across replicas before declaring rollout complete.

When to get help
