Cómo Un Hilo Más Fino Que Un Pelo Mueve El 99% De Internet Por El Fondo Del Océano

The cloud doesn't exist. More than 95% of the data that crosses from one continent to another travels through submarine internet cables laid on the mud of the ocean floor, four to five kilometers deep, where sunlight never reaches. In this documentary, we descend to that underwater internet you use every day without even knowing it. You'll see how a strand of fiber optic cable thinner than a human hair carries millions of calls and videos simultaneously, what repeaters are that revive the signal in complete darkness for 25 years straight, and why satellites can't compete with this internet infrastructure in capacity, cost, or speed. You'll also meet cable-laying ships, the few vessels on the planet capable of laying thousands of kilometers of cable in a single piece and retrieving a severed cable from the seabed with a hook, almost as they did in the 19th century. The story begins in 1858 with the first transatlantic telegraph cable and ends in today's internet geopolitics: anchors that leave entire countries without connectivity, earthquakes and volcanoes that cut off multiple routes simultaneously, a documented case of underwater espionage during the Cold War, and tech giants that no longer rent the lanes but build their own cables.
