Everything about telecommunications feels so instantaneous and global that most of us just assume satellites are the magic network that holds it all together. Sure, they stitch together vital parts of our networks but when you need to move heaps of data around the globe, it’s going underwater. Over 400 international cables stretch more than 550,000 miles (885.139 km) across the ocean floor and carry unfathomable amounts of data. The longest cable is SEA-ME-WE3, and moves data at roughly 575 gigabytes per second between 34 countries from Germany to Australia. SubmarineCableMap.com has an interactive map that lets you dive into the specs of every cable out there and explore how they connect the far reaches of the planet. Business Insider made this cinematic view of the same data which sprinkles in some fun facts along the way. And if you really want to get into the far corners of possibility, Gizmodo published a fun read back in 2012 about how one might theoretically be able to destroy the internet in which the cable network plays an important role.
