open up a bogus event with the odds 0 for one possibilty and the other with the odds 1000...I bet on 1 vcash on the 1000 and you 1000 on the 0...settle it and wallaaaaa
Your ISP will jump back and forth between the two servers IPs for a little while until it fully resolves (fully resolves = doesn't go back to the old server IP), I'm pretty sure that's what's causing it.
