Amazon, the One in 1000 Users

The answer about because the slowest response times would be the customers who purchase the most. So basically they tried to make sure that the response times are under 200 milliseconds. The reason was is that 1000th person had the most orders or that that one person out of 1000 that had the slowdown, theirs is going to load slower. And there's a massive drop off after you reach some threshold. But we don't have any patience. Nobody has patience.
