Ticket demand crashes Rockies' computers

Paciolan--acquired by Ticketmaster this summer and located just minutes from Special Ops Security HQ in Irvine, California--provides venue ticketing services to the Colorado Rockies professional baseball team. A little more than an hour after online ticket sales started this morning, the crushing load of 8.5 million requests crashed the entire North American ticketing system (affecting all of Paciolan's customers). This, just days after they assured uneasy fans that because MLB.com hosts their website, they would be able to handle the demand. What they failed to mention is that MLB.com only hosts the links to evenue.net (Paciolan).

For the first time in the Colorado Rockies baseball team history, they make it to the World Series... and the network engineers didn't believe that there would be overwhelming demand??

Furthermore, the system wasn't properly isolated such that a failure for one customer (the Rockies) would be isolated from other customers. Again we see that you don't always need fancy SQL injection skills to bring a system to its knees... sometimes you just need to open up your web browser (with a few million of your friends).
