I signed up for the new (gs) service a couple of weeks ago. The service right now is very unreliable, I’m getting database time-outs every few hours or so. I’m going to stick with it, as Media Temple have a great reputation, I’m sure they will get things sorted out.
This is of course a very new service and they have had a huge number of signups – I’m thinking more than they can handle right now.
If you are coming across issues with the site, my apologies, I’m hoping everything will be cleared up very soon.
