The book Tubes: A Journey to the Center of the Internet
by Andrew Blum is an exploration of the physical Internet. In this book Blum makes a pilgrimage to the
actual physical things that make the Internet we all use and love work. This book is a fascinating, if very basic
look at the Internet’s infrastructure.
It is definitely aimed at the beginner though, I found myself wishing
for a few more details and a little less gossipy chat.
