If the existing server people can speed things up the move won't happen, but if they can't, speaking from a personal point of view I can't live with this snail-like slowness. And if it's annoying me, I'm sure it's getting to everyone else too - all credit and thanks to everyone who has stuck around for the last few weeks as I wouldn't be surprised or blame anyone if this type of virtual-stop speed drove people away (please don't go anyone though

).
There were a number of technical and timing reasons for the extended down-time in the move that's just occurred. If there is another big move, I am virtually certain that with a bit of planning I can get it done with a maximum down time of 2 days and it's possible that it could be done with zero down-time (although the zero down-time would probably involve a couple of days worth of posts which would be lost in the transition period).
