Tubes. Behind the Scenes at the Internet; Penguin, 2013

The Internet. Home to the most important and intimate aspects of our lives. Our careers, our relationships, our selves, all of them are out there - online. So ... where is that exactly? And who's in charge again? And what if it breaks?

In Tubes Andrew Blum takes us on a gripping backstage tour of the real but hidden world of the Internet, introducing us to the remarkable clan of insiders and eccentrics who own, design and run it everyday. He uncovers the secret data warehouses where our online selves are stored, peels back the wires that transport us across the globe, reveals its mammoth hubs and surprising alley-ways, explaining what the Internet actually is, where it is, how it got there - and, yes, what happens when it breaks.
