Someone Is Cutting the Cables That Run the Internet

Someone is cutting the internet — and the infrastructure carrying the world’s data is sitting beneath the ocean. More than 99% of international data traffic travels through submarine telecommunications cables, making undersea cables one of the most important parts of the global digital infrastructure. These fiber-optic cables connect continents and support everything from internet access and cloud services to financial transactions, government communications and international business. In this documentary, The Fault Line investigates the hidden vulnerability of submarine internet cables, undersea cables, critical infrastructure and global communications networks. We begin in the Baltic Sea, where a series of incidents involving telecommunications cables, power infrastructure and commercial vessels has raised major questions about cable security, maritime activity and the protection of critical underwater infrastructure. The story then moves to Taiwan and the Matsu Islands, where repeated cable disruptions have highlighted the vulnerability of isolated communications networks and the growing importance of submarine cable security, maritime surveillance and geopolitical risk. But undersea cable warfare is not new. This video also looks at the history of cable cutting, the vulnerability of global communications, the 1884 international cable-protection framework, the difficulties of investigating damage at sea, and the limited number of specialized vessels available to repair damaged submarine cables. The bigger issue is the rise of hybrid warfare and grey-zone activity — actions that can create real strategic and economic disruption while remaining difficult to attribute. The European Union and international organizations are now treating the resilience of submarine cables as an important critical-infrastructure issue. And the consequences go far beyond losing your internet connection. A serious disruption to the right group of submarine cables could affect financial systems, cloud infrastructure, government communications, international business, military communications and everyday connectivity. The global cable network is enormous, but critical routes can still be concentrated in vulnerable geographic corridors. So the real question is: What happens when the world's most important infrastructure is almost completely invisible? And what happens if multiple undersea internet cables are damaged at the same time?
