“In the family tree of professions, submarine cable work occupies a lonely branch somewhere between heavy construction and neurosurgery. It’s precision engineering on a shifting sea using heavy metal hooks and high-tension lines that, if they snap, can cut a person in half.” If they snap, they could also cut off your internet. A huge amount of internet data travels via underwater cables that run along the ocean floor. If something goes wrong, your connection with the world could sleep with the fishes. The Verge with an excellent interactive piece on The Cloud Under the Sea. “The world’s emails, TikToks, classified memos, bank transfers, satellite surveillance, and FaceTime calls travel on cables that are about as thin as a garden hose. There are about 800,000 miles of these skinny tubes crisscrossing the Earth’s oceans, representing nearly 600 different systems, according to the industry tracking organization TeleGeography. The cables are buried near shore, but for the vast majority of their length, they just sit amid the gray ooze and alien creatures of the ocean floor, the hair-thin strands of glass at their center glowing with lasers encoding the world’s data. If, hypothetically, all these cables were to simultaneously break, modern civilization would cease to function.” (In my house, if Netflix buffers, my family ceases to function.)
