ARC2 Proxy
Load balancing Routing rule boolean

enable_health_checks

Actively probe backends and remove unhealthy ones from rotation.

boolean
Default
false

When enabled, the proxy periodically probes each backend and stops routing to any that fail, returning them once they recover. Essential for real failover — without it a dead backend keeps receiving (and failing) requests.
