I don't think it matters if it was a k8s issue or not, what matters is that k8s made it much harder to get to the bottom of it.
We actually had similar issues when we deployed k8s. In the end it turned out to be a misconfiguration, but took weeks to figure out, and only because our entire dev team looked at it (and not the k8s guru who implemented it all).
