Subsea cables form the physical backbone of the global internet, carrying over 95% of international data, yet they are highly vulnerable to both accidental damage and deliberate sabotage.
The industry has shifted from telecom-led consortiums to being dominated by hyperscalers like Google and Meta, who now fund and build their own high-capacity networks to connect their data centers, driving innovation but also concentrating control.
Geopolitical risk is a primary concern, with state actors like Russia and China implicated in targeting cables, and military strategists viewing them as primary targets in potential conflicts, such as a Chinese siege of Taiwan.
The process of repairing severed cables is a surprisingly analog, slow, and logistically complex operation, relying on a small, specialized fleet of ships, which creates a critical bottleneck and highlights disparities in internet resilience across the globe.
