Alentus is the Best. they are available 24/7 through tickets and chats.
My site is hosted by Alentus since 2012 and everything works fine for me, I don't know why the other users are complain for this issues, I never had this problems with Alentus.
I think Alentus has the best tech support that I've ever seen.
