I expect to hear a lot about the "wonderful" idea of moving running VMs 100 msec away (across the continent) in the upcoming weeks. I would recommend you read a few of my older blog posts before considering it... and don't waste time trying to persuade the true believers with technical arguments -- talk with whoever will foot the bill or walk away.
