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.
In June this year, a single fishing trawler severed three undersea cables off the coast of Egypt, cutting data flow to the Middle East and parts of Asia for days. The ship, flying under a flag of convenience, paid no penalty. 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. In 2021, a ship anchor in the Red Sea cut four cables simultaneously, 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. A 2023 study found that cable breaks near fishing grounds cluster precisely 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. One Chinese general wrote in a defense journal that cable routes represent strategic chokepoints. 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.
Yn juny dit jier snee in inkelde fiskersjacht trije ûnderseekabels troch for de kust fan Egypte en ferbra de gegevensstream nei it Midden-Easten en dielen fan Azië foar dagen. It skip, farjende ûnder in flagge fan gemak, betelle gjin boete. It ynsident iepene wat yngeniieurs al jierren witte: de buizen dy't 99 persint fan de wrâldwide interkontinintale gegevens drage, lizze op de seeflier mei amper gjin beskerming. In glasfiberkabel sa dik as in tuinslange ferkarret terabits oan ynformaasje, mar in anker, in fisnet of in baggerboat kin it yn sekonden trochsnee.
Kabelbreuken bart hieltyd. Gegevens sille om de 200 snidingen per jier wrâldwide, hoewol de measte ûnopmart bliuwe foar normalembrûkers om't it systeem redundânsje hat ynboud. Wannear't mearere kabels tagelyk fallje, ferleaze hiele regio's de ferbining. Yn 2021 snee in skipaanker yn de Roade See fjouwer kabels tagelyk troch, wat de kommunikaasje yn Oast-Afrika wiken lang stikke. Fersekearingsjiskaimen berikke miljoenen dollars, mar de echte kosten falle op bedriuwen, sikehûzen en regearringen dy't fan ûnûnderbroken gegevensstream ofhingje. Techbedriuwen lykas Google, Meta en Amazon ynvestearje no yn kabel-eigendom om't se de status quo net fertrouwe kinne.
De ynfrastruktuir hearre ta in lappendeken fan ûnderseekabeloperators, telekommunikaasjebedriuwen en regearringen. Nemo hat dúdlike ferantwurdlikheid foar beskerming. Ynternasjonaal maritym rjocht stiet ta dat skippen hast oeral op de open see anker lete. Fiskerijskippen yn in protte lannen operearje sûnder gode traceringssystemen. In stúdzje fan 2023 toande oan dat kabelbreuken tichtby fisgrûnen krekt klustere dêr't handhaving fan marityme regels faalt. De wolstannige nasjes dy't it meast profiteren fan wrâldwide gegevensstromen hawwe paad daan om monitoring of foarkoming te finansieren, en bejegne kabelskea yn stee dêrfan as in okkasyonel unbeheinich.
Militêre strategisten besprekke nû iepen ûnderseekabels as doelen. Tidens it Oekraïne-konflikt, maakten NATO en Ruslân har both soargen dat sabotaazje fan kabels dy't gegevens tusken Jeropa en Noard-Amearika drage, de westske kommunikaasje kuollen lammenje. In Sineske generaal skreau yn in defensjetydskrift dat kabelroutes strategiske knepitten fertsjintwurdigje. Dit binne net mear wilde teoryen. De kwetsbaarheid is echt, en geopolitike rivalen kenne it. Dochs hawwe regearringen noch altyd gjin uniforme reaksje, gjin rappide reparaasjemekanism, en gjin serieuze ynvestearrings yn kabels hurder te skeadigen.
De oplossing bestiet mar fereasket jild en koördinaasje dy't in pear wolle biedje. Ferstevige kabelhoezen yn ondjip wetter, better oerflaktokesicht, strikte marityme regels yn sônen mei folle ferkear, en reparaaskepskippen foar fluchtige respons kuollen de skeasnelheid dramatysk werleegje. Yn stee dêrfan wurde kabels noch altyd op deselde manier oanlein as desimber lyn. Salang't gjin grout oanfal of breed fersprieide falesstorring regearringen ta aksje dwingje, ferwachtsje neat om te feroarjen. De ruggestrjitte fan it internet lit unbewacht op de osjeanflier, wachtjend.
