DNS Failover Policy

机器辅助翻译草稿 (Chinese) for "DNS Failover Policy": DNS Failover Policy is a networking resilience policy that defines when traffic should move to another path or region for name resolution and delegation. 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.

“示例草稿: The network engineering team used DNS Failover Policy when a resolver returned stale data, so the team could recover from outages predictably before traffic crossed a service boundary.”
