ExpressRoute all regions vs all regions in geopolitical region.

In the #Azure-fundamentals learning path, in the "Describe Azure compute and networking services" section, on the "Describe Azure ExpressRoute" ( https://learn.microsoft.com/en-us/training/modules/describe-azure-compute-networking-services/11-expressroute ) page, in the "Features and benefits of ExpressRoute" section-- the first bullet states, "Connectivity to Microsoft cloud services across all regions in the geopolitical region."

The very next section's initial statements says, "ExpressRoute enables direct access to the following services in all regions."

So, without Global Reach, are we able to access the mentioned services in every region or every region within a geopolitical region?

Thanks

    Hello!

    Where am I seeing this?

    Subject: Exam AZ-900: Microsoft Azure Fundamentals

    Learning Path: Azure Fundamentals: Describe Azure architecture and services

    Module: Describe Azure compute and networking services
    Unit: 11 of 14 Describe Azure ExpressRoute

    What is the difference between ExpressRoute and ExpressRoute Global Reach?

    ExpressRoute and ExpressRouteGlobal Reach are slightly different things which causes some confusion. You can access Azure resources from anywhere in the world however ExpressRoute provides a high-speed connection to Azure. ExpressRoute Global Reach not only provides a high-speed connection to Azure, but also other networks like a data center or a corporate network. The diagram in the ExpressRoute Global Reach documentation makes this clearer.

    In our example here, a company has an office in San Francisco and London, as well as Azure services deployed to US West and UK South.

    Using ExpressRoute the San Francisco and London offices can both use high-speed connectivity to reach Azure services in either location. The San Francisco office has a speed connection to Azure services in UK South, for example, but not the London office.

    Using ExpressRoute Global Reach, both offices can use high-speed connectivity to connect to Azure services as well as other on-premises networks. The San Francisco office would have a high-speed connection to Azure services as well as a high-speed connection to the London office.

    Hi Mac,

    That text isn't clear enough in my opinion. What you can connect to depends on the ExpressRoute SKU. Local would allow you to connect to one or two local Azure regions, Standard allows you to connect to all Azure regions in geopolitical region, and Premium allows you to connect to all global Azure regions. Please see diagram:
