Chapter 1. Understanding zone failure

For the purpose of this section, zone failure is considered as a failure where all OpenShift Container Platform, master and worker nodes in a zone are no longer communicating with the resources in the second data zone (for example, powered down nodes). If communication between the data zones is still partially working (intermittently up or down), the cluster, storage, and network admins should disconnect the communication path between the data zones for recovery to succeed.
