Well Web King, if you would have ever bothered even just checking the main page of surespace before, you would have read that they are just starting out, and are in beta stages, therefore meaning that there would be some downtime while they work out the kinks in their server, they don't plan on officially opening until early to mid summer.
ilya- sorry about that, at one point on the main page, they just had all their features listed, once they got everything semi-working, they went back to the already available/coming soon listing of the features, mySQL being one of the features that they are still working on.
