Haven't had a chance to watch the video, but there is some great information in the notes.

"ServerBeach had two pipes, one for redundancy, and YouTube was using one and a half of them, with rest of its customers limited to just half of the one left. ServerBeach had a great plan, $129 month for unlimited data."

On a 10mbit pipe that's around 3000GB/mo max - the "non-unlimited" (for a bit less $) would have been 2000GB.

“YouTube didn’t have PowerPoint, just product and stats, when it made the rounds on Sand Hill Road.”
