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.

Last week, we wrapped up a five-part podcast special that literally explains how the internet works.

This series describes precisely how data moves around the world, covering the basics of internet, transport networks, data centers, the cloud, and WAN along the way.

At the end of each episode, I thought it would be fun to relate what we talked about to a real world example: the lifecycle of a YouTube video.

To paint the full picture, I've compiled each piece of the story here. Keep reading to find out how a video goes from one camera to millions of screens around the world.

When it comes to the nature of exploration, there are typically a number of underlying forces at play, some positive and some negative.

The “pioneering spirit” could be inspired by the excitement of new opportunities, or by the pressure of existing difficulties.

The data center market happens to be dealing with both of those sentiments right now, with several factors driving it to new places.

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.
