The Underwater Cables That Carry the Internet Are in Trouble

The roughly 500 fiber-optic cables lying on the ocean floor carry more than 95% of all internet data -- not satellites, as many might assume -- and they face growing threats from natural disasters, terrorists and nation-states capable of disrupting global communications by dragging anchors or deploying submarines against the infrastructure.

The cables are protected by layers of copper, steel, and plastics, but they remain vulnerable at multiple points: earthquakes can disturb them on the seafloor, and the connections where cables meet land-based infrastructure present targets for bad actors. National actors including Russia, China and the US possess the capability to attack these cables.

A bipartisan Senate bill co-sponsored by Democrat Jeanne Shaheen and Republican John Barrasso is under consideration. The legislation would require a report to Congress within six months on Chinese and Russian sabotage efforts, mandate sanctions against foreign parties responsible for attacks, and direct the US to provide more resources for cable protection and repair.
