I know I am late in the game on this thread but I feel compelled to jump in. I tried C Class Ip hosting and they are the worst piece of crap hosting I have ever seen. They were hosting my blog network with pr.
Never failed every morning all of my sites were down. I had to submit a ticket every day. They never fixed the problem and I started to lose my pr when Goolge crawled my sites and they were down.
Skynet hosting has been great and as of yet my sites have never went down.
Damn that sucks man.. Sorry to hear that.
I have been lucky since I switched to hostgator a few years back. But I had to do alot of research before i realized they were the best choice for me.
Originally I had godaddy and I hated them cause you needed a PHD just to get into the settings and felt like they changed the way you logged in all the time so I could never figure it out.
