Understand why a Vultr Load Balancer serves only same-region instances and how DNS routing covers more regions.
Vultr Load Balancers operate at the regional level and can only distribute traffic to instances within the same region. This ensures low latency, predictable performance, and reliable health checks between the load balancer and its attached backend instances. You cannot attach instances located in different regions to a single regional load balancer.
If your application requires multi-region availability, you can deploy additional child load balancers in each target region and combine them with a global routing strategy. For example, you can use DNS-based load balancing with multiple Vultr Load Balancers (one per region) to distribute traffic geographically or provide failover. See the How to Manage Vultr Global Load Balancer Regions guide for details on implementing this approach.
