Summary:
Today, the website to get tickets for the 2012 Olympics was slowed down my massive demand. The site started taking order for tickets at 6am, after 1.2m people didn't get any in the first round. Because of the huge demand, the website went down and showed a popup saying "please try again later", even after submitting payment details. The other warning they got was to not refresh the screen if they say a popup with "high demand". A costumer said "It's such a shame the system works like this over here. If you look at Anthens, it's ridiculous that they can't implement the same ticket system here."
A statement on the London 2012 website said: "Demand is extremely high at the moment on the ticketing website but the system is still transacting.
"If you've clicked submit, don't hit refresh. Please wait and the system will process your order.

Personal opinion:
It's a weird system to begin with. You basically pay for something that you're not even sure you're going to get, and with this website failing... Well, that doesn't really help that much either does it. I think the costumer who said they should implement the same system they have in Anthens is right. Why does it work fine or there and why can't they make it work in the UK?
