ExpressRoute connectivity partners and peering locations

The tables in this article provide information on ExpressRoute geographical coverage and locations, ExpressRoute connectivity providers, and ExpressRoute System Integrators (SIs).


Azure regions and ExpressRoute locations are two distinct and different concepts, understanding the difference between the two is critical to exploring Azure hybrid networking connectivity.

Azure regions

Azure regions are global datacenters where Azure compute, networking, and storage resources are located. When creating an Azure resource, a customer needs to select a resource location. The resource location determines which Azure datacenter (or availability zone) the resource is created in.

ExpressRoute locations

ExpressRoute is supported across all Azure operated by 21Vianet regions and locations. The following map provides a list of Azure regions and ExpressRoute locations in China. ExpressRoute locations refer to those where Azure peers with several service providers.

China Location map

You'll have access to Azure services across all regions within a geopolitical region if you connected to at least one ExpressRoute location within the geopolitical region.

Azure regions and geopolitical boundaries for national clouds

The following table provides information on regions and geopolitical boundaries for Azure operated by 21Vianet.

Geopolitical region Azure regions ExpressRoute locations
China East China East
China East 2
China North China North
China North 2
China North 3

Connectivity across geopolitical regions isn't supported on the standard ExpressRoute SKU. You'll need to enable the ExpressRoute premium add-on to support global connectivity. Connectivity from Azure operated by 21Vianet to other Azure cloud environments isn't supported. You can work with your connectivity provider if such a need arises.

ExpressRoute connectivity providers

The following table shows locations by service provider. If you want to view available providers by location, see Service providers by location.

National cloud environment

Azure operated by 21Vianet is isolated from other Azure clouds. ExpressRoute for Azure in China can't connect to the Azure regions in the other Azure clouds.
