TeleGeography's Interactive Submarine Cable Map Is a Fun and Fascinating View Into Infrastructure

Dan York

TeleGeography Submarine Cable Map http://www.submarinecablemap.com/Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography at the easy address of: http://www.submarinecablemap.com/

It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. You can easily move the map around and zoom in on certain regions and click/tap on the lines to learn about specific cables. You can also select one of the cable names in the right sidebar to see the specific cable and its landing points, owners, length and date of service. Alternatively you can click/tap on one of the landing points and find out the name of the location and the list of all the cables going through that landing point. A search box is also available.

I admit to getting sucked into exploring the map for a while, given how easy it is to use. Submarine cables may not be among the top topics discussed on sites such as CircleID, but they are absolutely critical to providing Internet and telecom connectivity to many parts of the world. This site makes it so very easy to see where all the submarine infrastructure is deployed.

Kudos to the folks at TeleGeography for making this site available and apparently to Huawei Marine Networks for additional sponsorship. My one bit of feedback would be that it would be great if you could get a link for a specific cable that you could pass along to someone else or reference in a blog post or article — but that's a minor point and perhaps may be something that gets added.

What do you think? Do you find this site a helpful view of submarine cables? Are there other similar sites that you find useful, too?

Three additional notes:

1. This site has apparently been around for some period of time (i.e. it's not a "new" site, it was just new to me).

2. Interestingly, the folks at TeleGeography have made the source code for the website available at:
There are also links there to where to obtain the data sets used for the map.

3. A person at TeleGeography contacted me after this article was published to say that my feature request is indeed something they are considering for a future version of the site.
