The History of U.S. Telecom Policy (in Under 60 Minutes)

TeleGeography Explains the Internet is back from summer break.

We return a little older, a little wiser, and you can bet that we've done the summer reading. To that end, we're starting this season with a classic TeleGeography Explains deep dive.

The topic? U.S. telecom law! 

Telecom is a regulated industry, and U.S. law holds complexities that impact what happens across the larger ecosystem. I have a lot to learn about telecom policy, so thankfully I'm joined in this explainer by Jeff Long, an attorney in private practice with broad experience in both the data center and telecom industry.

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.

Welcome back to our five-part podcast special that seeks to demystify the internet. 

Our last episode focused on data centers, but we didn’t get into what happens on the rows and rows of servers you would find in those facilities.

So today we're explaining the cloud.
