Thank you Farjo.
Thank you too
As an aside I'd be asking your hosting provider a few questions:
1.) Why wasn't adequate notice given prior to the down time?
2.) Why was the down time required to move host at all?
3.) Given most of these things are virtualised why was a dns change required?
4.) Why was your data lost?
I'm sure this operation isn't done on a shoe string so I'm at a loss to understand why their changes were implemented so poorly.
Maybe you can get a few months free with the right complaint
