The FBI has opened an investigation into the Colorado Rockies' claim of an "external, malicious attack" on computer servers that brought down the club's first attempt to sell World Series tickets.
Computer servers handling the online-only sale were overwhelmed by 8.5 million hits in the first 90 minutes Monday, paralyzing the system and forcing the Rockies to suspend the sale.
FBI spokeswoman Laura Eimiller in Los Angeles says the bureau is opening up a probe into the possible compromise of a Web server in Irvine, California. The servers is operated by Paciolan, which handled the ticket sale.
MLB.com executive Bob Bowman has said the system was overloaded by powerful computers programmed to constantly generate five-digit codes meant to prove a real person is trying to buy tickets.
Bowman says those computers were blocked from buying tickets, but their attempts to connect were NOT discarded, allowing them to clog the system and ultimately knock it down.
The Rockies' second attempt went better, with fans snapping up more than 50,000 tickets in two-and-a-half hours on Tuesday.
