k8s does not have a way to expose a global load balancer with TCP endpoints, and setting up node port-based routing is a chore, even with Terraform (which is what we did with the standalone proxy). We will use Cloud DNS's geolocation routing policy to ensure that clients connect to the endpoint closest to them.
