Move a static public IP between Droplets in seconds without DNS changes, but know what failover does and doesn't protect.
Learn how Pod Disruption Budgets protect your Kubernetes workloads during voluntary maintenance like node drains and autoscaler scale-in, with a concrete three-replica example and the deadlock trade-off to avoid.

PodDisruptionBudgets limit voluntary evictions during maintenance, but only if the selector matches your pods and you know what they can't prevent.
A Pod Disruption Budget caps how many replicas can be evicted during voluntary disruptions like node drains. Learn how minAvailable and maxUnavailable work, see a worked manifest, and verify the budget before your next cluster upgrade.
Intermittent 500 errors and stale pull‑request data across Bitbucket Data Center nodes usually indicate cache or shared‑home incoherence. This guide shows how to confirm node‑specific drift, map symptoms to causes, and apply targeted fixes with safe verification.
