The Underwater Cables Powering Global Life

Almost the entire global internet relies on fragile fiber-optic cables resting on the ocean floor. These thin lines carry nearly all international data, meaning your digital life travels through pipes thinner than a garden hose.

While we think of data moving through satellites, over 99 percent of international communications actually flow through these deep-sea submarine cables. They are surprisingly vulnerable, often no thicker than a soda can and prone to damage from curious sharks or heavy ship anchors. Despite their extreme importance to global finance and social connection, they are rarely seen or discussed. It is incredible how the modern world functions solely thanks to this hidden, underwater web.
