Investment in new submarine cables has surged in recent years. Despite some fluctuations, new cable investment has averaged over $2 billion per year in the past eight years.
With demand continuing to rise at an exponential rate, the value of new submarine cables entering service from 2024-2026 is forecasted to reach over $10 billion.
To many people, the concepts of global network infrastructure and bandwidth markets are difficult to grasp. But to those who follow this sector, it's one of the most fundamental building blocks of the global economy.
If you haven't heard of TeleGeography’s Transport Networks Research Service, it's one of our most popular research subscriptions. In short, this tool assesses the state of the global telecom capacity market—and we just finished updating it with tons of new data and analysis.

Today, I'm breaking down three fundamental components of cloud networks.
As if three cable faults in the Red Sea weren’t enough of a headache, a series of West African cables were damaged on March 14.

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.
This month, we’ve seen countless headlines swirling about Houthi attacks and submarine cable faults in the Red Sea.
