Key points
- •Traffic dial percentage controls how much proximity-eligible traffic actually reaches a given endpoint group
- •Health checks run continuously per endpoint group, independent of geographic routing logic
- •An unhealthy group is automatically excluded from routing, redirecting its traffic to the next-best healthy group
- •Failover completes at the network layer in well under a minute, with zero DNS propagation delay
