Meta has announced Project Waterworth, a previously-rumored “multi-billion dollar, multi-year” plan to build an over 50,000-kilometer undersea cable to support AI infrastructure. It would be the world’s longest, designed to resist “damage from ship anchors and other hazards.”
Its planned route snakes from the east to west coasts of the US at up to 7,000 meters deep, connecting to Brazil, South Africa, India, and Australia along the way.
