How Undersea Cables Became the Most Vulnerable Part of Global Communications
September 25, 2025 · Frisian News
Ninety-nine percent of intercontinental data travels through undersea fiber optic cables, yet these vital lines remain exposed to ship anchors, fishing nets, and potential sabotage. Governments and tech giants have largely ignored the risk until recent cuts exposed the fragility of global internet infrastructure.
A vessel severed undersea cables off the coast of Egypt, cutting data flow to the Middle East and parts of Asia for days. The incident revealed what engineers have known for years: the pipes that carry 99 percent of the world's intercontinental data lie on the seafloor with almost no protection. A fiber optic cable as thick as a garden hose carries terabits of information, yet an anchor, a fishing net, or a dredge can slice through it in seconds.
Cable breaks happen constantly. Records show around 200 cuts per year worldwide, though most go unnoticed by ordinary users because the system has redundancy built in. When multiple cables fail at once, however, entire regions lose connectivity. A ship anchor in the Red Sea cut cables, strangling communications in East Africa for weeks. Insurance claims reach millions of dollars, but the real cost falls on businesses, hospitals, and governments that depend on uninterrupted data flow. Tech companies like Google, Meta, and Amazon now invest in cable ownership because they cannot trust the status quo.
The infrastructure belongs to a patchwork of undersea cable operators, telecommunications firms, and governments. Nobody has clear responsibility for protection. International maritime law allows ships to anchor almost anywhere on the high seas. Fishing vessels in many countries operate without proper tracking systems. Research has found that cable breaks near fishing grounds cluster where enforcement of maritime regulations fails. The wealthy nations that benefit most from global data flows have done little to fund monitoring or prevention, instead treating cable damage as an occasional inconvenience.
Military strategists now openly discuss undersea cables as targets. During the Ukraine conflict, NATO and Russia both worried that sabotage of cables carrying data between Europe and North America could paralyze Western communications. These are not wild theories anymore. The vulnerability is real, and geopolitical rivals know it. Yet governments still have no unified response, no rapid repair mechanism, and no serious investment in making cables harder to damage.
The solution exists but requires money and coordination that few want to provide. Reinforced cable sleeves in shallow waters, better surface monitoring, stricter maritime rules in high-traffic zones, and rapid-response repair ships could cut the damage rate dramatically. Instead, cables keep getting laid down the same way they have for decades. As long as no major attack or widespread failure forces governments to act, expect nothing to change. The internet's backbone sits unguarded on the ocean floor, waiting.
