We are all so accustomed to using the internet, searching the world wide web — "going online" — that most of us most of the time probably do not stop to consider the question: yes, but where exactly is it?
Andrew Blum DID ask that question, and it led him on a quest to find out exactly how the internet works on a tangible, physical level.
The result is a well-informed and highly readable account. While there have no doubt been developments in the twelve years since the book was published, I think it is still worth reading, specially in terms of the kind of wiring used and the hardware — at the outset the author is using a modem. Well-written and informative.
