map-of-the-nine-worlds

A map of all the world’s undersea telecom cables. “Ninety-nine percent of trans-oceanic data traffic, Internet traffic, goes underneath the ocean on the very bottom of the sea floor.” Why not by satellite? Lag: the speed-of-light delays from going up 22,000 miles to a geosynchronous satellite and back down are way too long.

My favorite cable is the far North one connecting Norway to the island of Svalbard. Armored polar bears need the Internet too.
