Region Boundaries for Azure Resource Groups

Q: Can an Azure resource group span regions?

A: Yes. An Azure resource group can span multiple regions. The resource group is a way to manage the lifecycle of multiple resources that are part of a single unit, with the resources being able to span multiple regions. An example is virtual networks. In the new portal you can see that all virtual networks are part of a single resource group, Default-Networking. Each virtual network can be in a different region.
