Global VNet Peering now supports Standard Load Balancer. Previously, resources in one virtual network could not communicate with the front-end IP address of an internal load balancer over a globally peered connection. The virtual networks needed to be in the same region. With this announcement, this is no longer the case. You can communicate with the internal IP address of a Standard Load Balancer instance across regions from resources deployed in a globally peered virtual network. This support is in all Azure regions, including Azure China and Azure Government regions.
Learn more about Standard Load Balancer and Global VNet Peering. Basic Load Balancer is not supported. We recommend moving to Standard Load Balancer to use this capability.
