Map of Undersea Internet Cables (opens in new tab)

When crossing the Atlantic and other big oceans, do the cables actually rest on the ocean floor or do they float?

like that map.. it's been on hn a few times. have it bookmarked.

This article has a similar map (same data source) with a slider by year: https://builtvisible.com/messages-in-the-deep/ (The article is also interesting)

Would be neat to add know and suspected Five Eyes interception points.

For people interested in this, I can recommend Neal Stephensons Wired feature from the 90's. As you'd expect from Stephenson, it's crazy long. It describes his travels documenting the laying of an early submarine Internet cable.

Also, this is quite informative: https://www.quora.com/How-are-major-undersea-cables-laid-in-...

The most connected spot in the world isn't New York or Hong Kong, but the unlikely city of Fortaleza, Brazil, with 17 cable landings.

It's really weird thinking about, that every time I swipe around that map on my phone, what I see is sent over some of those exact cables from the other side of the world.
