How Undersea Cables Became the Most Vulnerable Part of Global Communications

Undersea cables carry 99% of international data traffic but remain defended like telegraph lines. Russia and China have shown strategic interest in these systems, which private tech companies operate with minimal security.
Undersea cables carry 99% of all international data traffic, yet cables crossing the Baltic Sea have suffered several major cuts since 2023. The Russian research vessel Yantar, known for deep-sea espionage operations, has been tracked near undersea cables in the region. No one believed it was accident.
Tech giants own these cables. Google, Meta, and Amazon control most of the routes. A single cable transmits enough data for millions of simultaneous video streams. Private companies treat the infrastructure as a revenue stream, not a public utility. When a cable fails, entire regions lose banking, healthcare, and emergency systems. The owners pay nothing for security.
Fishing trawlers and ships accidentally cut cables. That happens. But Russian submarines have mapped cable routes with care. U.S. intelligence reports have indicated Russian special forces trained for sabotage against undersea systems. Questions have been raised about whether surveillance equipment was placed during cable repairs. These were not accidents of curiosity. They were planned operations.
Governments ignored the risk for years because the risk was profitable for cable operators. The EU finally ordered member states to treat cables as critical infrastructure. The U.S. Navy increased patrols in vital chokepoints. But these moves come after the damage. The real moment to act was years ago, when the pattern of incidents first emerged. Official sluggishness protected the profitable status quo.
Cables remain undefended because defense costs money and profit margins come first. Governments could mandate redundancy, bury shallow cables, and deploy armed escorts. Instead, we built civilization's digital backbone and abandoned it. When the next cut happens, call it infrastructure failure. Call it an act of war. Just do not call it unforeseen.
