HOLY CHRIST!!! YOU ARE RIGHT ON THE MONEY! Except for the isprime part (I wouldn't know cause I have never been with isprime) But, you are right on the fucking nail about iicinternet.com. They are the WORST, and I do mean WORST hosting company out there. Tech support that gives you the run around, cogent bandwidth, server downtime that can go on for 10 hours at a time and server speed that makes your grandma look as fast as a monkey with a rocket up her ass.
Damn, I hate iicinternet.com. This is JUST my opinion, but I would HIGHLY RECOMMEND not hosting with them... even if they are really cheap, you'd be better off somewhere else.
