A lot of Japanese websites also have to be tremendously over provisioned because of how regimented the country is. A friend of mine worked infrastructure for a local newspaper, and every day at 6PM they'd send a push notification to all their subscribers and had to provision for that peak. When he asked if they could smooth out traffic, send the notification to some folks a minute before, or a minute after he was almost thrown out of the room. "Japan runs on time. Not a minute early, not a minute late. On time".
