There really isn't that much in it when you're talking world connectivity. US MT has long been the best place to host for global servers, its only very recently European Datacentres have caught up in terms of pipe accessibility. EVE is an exception due to how it was conceived, the nature of the playstyle and staff location, and the fact that the US uptake in EVE has never been particularly large, unlike here in Xsyon.

If this was an FPS with heavy ping dependency you may have an argument, but when the majority of the EU can happily connect with around 100ms Ping on a decent network provider, I doubt youre going to prompt any kind of server move less than a week before launch.

You would have better results contacting your ISP to arrange a better route for you if you require it.
