The Internet Is Mostly Underwater (Here's Why)

The Internet Is Mostly Underwater The internet isn't in the cloud — it's on the ocean floor. Nearly 99% of all intercontinental data is carried by roughly 850,000 miles of submarine fiber optic cables, and they're more fragile than you'd expect. This video covers the history of undersea cables from the 1858 transatlantic telegraph to modern fiber optic networks, the surprising vulnerabilities of global internet infrastructure, and the rise of underwater data centers from Microsoft's Project Natick to China's commercial seabed servers. Submarine cables, internet infrastructure, and underwater data centers are reshaping the future of the global internet. 00:00 - Where Is the Internet? 01:09 - Transatlantic Cable History 02:15 - Fiber Optics & TAT-8 03:04 - What Cables Look Like 04:30 - Cable Vulnerabilities 06:38 - Big Tech Owns the Cables 07:30 - Microsoft Project Natick 10:13 - China's Underwater Data Centers 11:13 - Geopolitical Stakes #internet #technology #submarine #infrastructure #datacenter
