Reddit POTUS IAMA Stats

Coolest part of the post is actually the map of traffic by city and hour: http://www.webgl.com/reddit-webgl-barack-obama-ama-globe/. NYC at 5PM is crazy.

i would like to see more in terms of specs of whats going on with the load balancing and why it wasn't able to scale. Also, why was it down for some users but just slow for others? I don't have much experience with that so I am curious.
