Isn’t it millons of teeny tiny reconnections?
In: Engineering
Which one? [There are a lot of undersea cables](https://www.submarinecablemap.com/), and each one is designed to last at least 25 years. Old ones can get pulled up, but they’re usually just left on the ocean floor. There are some companies that will try to acquire the salvage right to them and pull them up for raw material recycling, but most of those materials get sold back to the companies that made the cables in the first place and re-used into new ones. Modern cables have diagnostics built in so whenever one starts having troubles they can tell where and replace just the malfunctioning segment instead of writing the whole cable off and laying a new one.
