Answer
PDB applies only to voluntary disruptions; node crashes bypass it.
Quick Answer
PDB is enforced only during voluntary disruptions processed by the Eviction API — drain operations, cluster upgrades. Node failures are involuntary — the node goes down hard, and Kubernetes terminates all its Pods immediately without consulting PDB. Use Pod Anti-Affinity across nodes/zones to ensure replicas are physically separated — that's your protection against node failures.
