The Internet isn't only on your screen. Or behind your couch. Or in Google's data centers. It's also underwater, where fiber-optic cables stretch across oceans and loop around continents.
Satellites are like dial-up. Nobody uses them. Undersea cables make the Internet global, with the most sophisticated of them capable of transmitting nearly ten terabits of data per second, compressed through just a handful of fiber-optic strands. There are only hundreds of these cables in waters around the world. And they are all preposterously proportioned, as thin as a garden hose and as long as-actually, nothing. No human construction matches them. They are the longest tubes ever made, and, for the first time ever, there's a truly accurate interactive online map of them.
For a decade, Washington DC-based Telegeography has been publishing an undersea cable map. But it's always been on paper, delivered in a cardboard tube, and sold for $250. But starting today (right this second, actually) the company has put its map online, for free, and made it interactive. And rather than scraping data from Wikipedia, Telegeography's Internet cartographers get information the old fashioned way: They ask the cable owners, who happily share the location of their landing stations and the current bandwidth capacity of their systems.Full report :
