What Happens When an Undersea Internet Cable Breaks?

An undersea cable breaks. Networks look for another path, while a specialist crew prepares to restore the physical connection. Follow a request from your phone to a cable landing station, see how light carries data through glass, and watch the repair move from the seabed to a workshop aboard a cable ship. One break does not switch off the global internet. The experience depends on your provider, destination, alternative routes and available capacity. This factual explainer uses original drawings to explain a typical cable-section repair, not footage of a particular incident. There is no universal repair countdown.
