Description: Tubes: A Journey to the Center of the Internet examines the physical infrastructure behind the Internet, including data centers, key locations, and the individuals involved in maintaining its global connectivity
"Tubes: a Journey to the Center of the Internet" by Andrew Blum[1] examines the transatlantic cables from a historical perspective, along with the rest of the internet. It's not especially technical and he talks about a dead squirrel maybe a few too many times, but it's a pretty good read. I wrote a review about it a month ago[2].
