In this episode, we find out how a system of cables around the globe (and deep in our oceans) brings websites, songs, videos and podcasts to our phones and computers, almost at the speed of light. The internet can seem vast and intangible but there’s a very physical system of cables, servers and exchange points across the globe (and yes, even under the oceans).
