Subsea cables carry over 95% of global internet traffic, yet remain one of the least secured layers of global infrastructure. These vital conduits for data sovereignty pass through a small number of vulnerable maritime corridors — many shared with traditional naval chokepoints. Mayfair’s sovereignty lens treats digital infrastructure as critical terrain: exposed to sabotage, surveillance, and denial operations.

This briefing isolates key undersea fault lines where physical, geopolitical, and legal risks converge. We map continuity threats from cable landing station clustering, regulatory asymmetry, and escalating gray zone contests over subsea terrain.
