A deep dive into Internet infrastructure, plus a visit to a subsea cable site
10 terabits per second on a single strand.Amazing.   I think if people back in 2000 would have realized the capacity coming along in fiber, then a site like youtube would have been obvious to many more people.  Back then, I think a lot of people thought it would be cool to have a video distribution site... but how the heck would you pay for it.  I remained amazed and confused by how Google could somehow afford to embed video on every random website -- becoming the video provider of the entire Internet.  But I guess for them it was a simple formula of using their excess capacity for something.Amazing.
