Undersea cables that ferry 99% of global internet and AI traffic are under threat from sabotage in the Strait of Hormuz, a risk that could cripple offshore renewable energy transmission and disrupt digital services in India. The potential loss of a single link could cut 60% of the country's internet traffic, underscoring the strategic importance of these subsea assets. The subsea network is expanding rapidly, with 119 new cables expected in 2026 compared to 66 in 2020. Each year, 150 to 200 accidental cuts occur, largely from fishing or geological events, while the cost of installing a power cable ranges from $1.2 to $3.5 million per kilometre and $29,000 to $53,000 per kilometre for data lines. The industry's resilience measures include distributed acoustic sensing, turning optical fibres into long-range microphones that detect nearby vessels, and sonar arrays that monitor cable surroundings. Despite these safeguards, the International Cable Protection Committee's chairman, Dean Veverka, warned that "the submarine cable industry goes to great lengths to protect cables, provide resilient networks and minimise disruptions… bad actors too can cause disruptions if they really wanted to." Governments and private firms are boosting investment in monitoring technologies and expanding redundant connections to enable rapid switchover in emergencies. International cooperation on subsea cable policy could further reduce sabotage risk, ensuring the continuity of both energy and data lifelines.
