I moved to blazingfasthost after reading reviews and having a terrible experience with my previous host.
The availability of both live online support and phone support is fine. As far as the up-time, it is very good.
And I have never had a problem using their control panel. I have been using them for half of a year now and must say that this experience has been great. So far, I am extremely impressed with these guys. There is nothing that counts more than decent support and they go beyond the call.
