iPhone: O2 Faced 13000 Pre-Orders Request Peaks per second

Last Monday, O2 was allowing users to pre-order their iPhone 3G online. This initiative did not last more than couple of hours, as the dedicated website was quickly saturated and the stock of iPhone 3G run out. O2 made the story public, announcing to have faced peaks of up to 13000 pre-order requests per second on Monday morning. Despite having increased by 250 fold the capacity of their server for the pre-order website, it could not support the request rate so long.
