The Internet Is Underwater

Almost all international internet traffic travels along cables lying on the sea floor, which break regularly and are repaired by ships.

The internet lives underwater. Send this to anyone who still says everything is in the cloud. Nearly every message that crosses an ocean does not fly anywhere. It travels along cables lying on the sea floor, in the cold and the dark, beside fish and crabs.

The cables are thinner than people expect. Far out in deep water, where almost nothing can reach them, some are no thicker than a garden hose. Inside are hairs of glass, and light runs along that glass carrying photos, calls, films and every word you send to another continent.

Things break them. Not sharks, although a shark did chew one once and the story has never died. Mostly it is fishing gear and heavy anchors dragging along the bottom. It happens more than a hundred times a year, somewhere in the world. Then a ship sails out, finds the broken line, lifts it up from the sea floor, joins the glass back together and lowers it down again. The cloud, it turns out, gets seasick.

That's the story.
