The internet has a seemingly infinite number of edges, but a shockingly small number of centers.


The internet has become a big place. Over 1 billion websites are live right now, every day over 100 billion (!) emails are sent, and 3 million blog posts are published in a 24-hour period. Chances are the internet is a self-evident, natural part of your life. But it's still not for everyone.

There are about 3.5 billion internet users worldwide, meaning that half of the world's population is not online yet. Can you imagine how big things will get as we slowly connect everyone to the web? Facebook has already dedicated itself to this mission.

While the sheer size of the internet is enough to make your head spin, there might be one thing that's an even bigger mystery. Where is the internet? Like, physically. Do you know the answer?

Sure, cables, servers, but where? And how they're connected? No idea. Until now.

Tubes by Andrew Blum is the light brought to the darkness of the internet's physical structure.
