Let’s Get Physical: Where Do Carriers Offer Network Services to Enterprises?

The geographic coverage of carriers’ enterprise network services varies significantly.

Not every carrier connects to every city in their customers’ networks, and not all services are available everywhere.

When narrowing down the universe of potential suppliers, enterprises must first consider how their geographic requirements overlap a potential service provider’s physical network. They then must determine if the specific data services they require are enabled at each of the service providers’ PoPs.

The WAN Services Coverage analysis—one section of our Cloud and WAN Research—examines carrier network connectivity and service availability from a geographic perspective.

Keep reading for a sneak peek of our latest findings.

Towards an Interconnection Index: Ranking the World’s Greatest Hubs

At TeleGeography, we’ve been working on a project called the Interconnection Index. This tool is designed to answer some questions that we’ve found very difficult to answer and quantify in the past.

What is the next emerging hub in a specific region? How do various hubs compare to each other? Where should I expand in a certain country besides the largest city?

It would be quite challenging to create a one-size-fits-all model that can answer all of these questions appropriately. But we’re still going to try!

We’re going to address this problem with data, and—because we’re geography geeks—maps.
