That is one of the oldest service providers over there and I'm certain that it has plenty of reviews.
Do the search here.
Just note reviews - that is what other people think or feel about the company - your own feelings and thoughts might be different.
Volume based business models can be tricky. When you need reliability you some times have to dig a little bit deeper. Hosting is critical and should be budgeted for appropriately. It's not to say that there can't be good hosting for little cash but it should be regarded highly.
These days they change the ip address of web hosting so frequently. Each time make my websites down for hours!
A change of IPs isn't enough of a reason to justify extended downtime. So, it seems they're just not doing their job right.
I haven't used Fatcow in over a year, but based on my experience with their slow servers, and then a similar one with one of their sister brands, iPage, I can only suggest you stay away from them as well. Definitely ask any host if it uses the vDeck control panel. Take that as an indication that they're probably part of the same group of hosts, and be extra vigilant.
