I've used iPage before. They were down pretty regularly every day for me. So much so, that I abandoned it after less than a week. I've since moved to a Digital Ocean server and Namecheap for domain registration, and I've never looked back.
I have several sites with them and have never had an issue. How long ago was this?
It's admittedly been two or so years, so their infrastructure may have undergone some real revision.
