Subnet Failover Policy

Subnet Failover Policy is a networking resilience policy that defines when traffic should move to another path or region for address segmentation. It uses health signals, priorities, and cooldown windows so teams can recover from outages predictably while keeping evidence, reliability, and public-safe operational boundaries clear.

“The network engineering team used Subnet Failover Policy when a workload moved networks, so the team could recover from outages predictably before traffic crossed a service boundary.”
