There's been lots of conversation about the recent boom in submarine cable construction. This flurry of activity becomes clearer when our annual map is viewed over time.
TeleGeography’s Submarine Cable Map recently hit a new milestone: depicting over 650 cable systems.
As of February 2025, that’s a whopping 570 in-service systems, with another 81 planned.
The number of cable systems we study is constantly increasing. This is due to massive investment in this infrastructure—both along major routes and to small islands—as well as our ongoing efforts to track global systems in more detail.
The number of in-service systems is greater now than in any other year within the last two decades.

The 2025 Africa Telecommunications Map is out—and it pairs perfectly with this year’s Submarine Cable Map.
Happy New Year? Now it is, because we just dropped our 2025 Submarine Cable Map.
Sponsored by Telecom Egypt, this futuristic, high-contrast design depicts 597 cable systems and 1,712 landings that are currently active or under construction.
If you’re a regular on this blog, you're probably familiar with our submarine cable and cloud infrastructure maps.
But you may not know about the third tool in our interactive map tool belt: the internet exchange map.
The TeleGeography Submarine Cable Map is our longest-running map project. We started producing submarine cable maps in 1999, and we're still going strong 25 years later.
Just for fun, let’s compare the very first edition—called the Global Communications Cable and Satellite Map—to our 2024 Submarine Cable Map.
If you're not familiar with TeleGeography’s Cloud Infrastructure Map—a free tool that tracks cloud data centers and on-ramps both built and planned—now is a great time to get acquainted.
Why, you ask? When our team updated the Cloud and WAN Research Service for 2023, the Cloud Infrastructure Map also got a refresh.
Keep reading to get the lowdown on our latest version and why you ought to be using it.
While our interactive submarine cable map is updated on a rolling basis, printed editions are unveiled annually. Each edition has a different theme, and our team always tries to out-do last year’s release.
Can you guess what inspired our latest design?
There's a good chance that you first heard about TeleGeography through one of our maps. Research Analyst Lane Burdette was introduced to TeleGeography when she came across our Submarine Cable Map a few years ago.
Now part of the team that creates this resource, Lane is understandably excited about this week's 2023 Submarine Cable Map launch. It seems like the perfect time to welcome her and Designer and Cartographer Larry Lairson to TeleGeography Explains the Internet.
Early in the calendar year is map design season around TeleGeography. Colorful proofs arrive at the office, which the design team pores over, so as not to miss any details. No cable left behind. No design flourish left unexamined.
So when the DC office packed up and transitioned to remote work in March 2020, we were left to wonder: how were we going to finish our cable map from within quarantine?
