My Company is using Citadel Servers for the past one year for our customers and we have received so many good reviews about it that there is no down time, Faster than other hosting like host havoc for game hosting or godaddy for webhosting and others and the main thing which I love about it was that we were able to customise the server as per our needs. I would recommend their services to all webmaster and web hosting companies or if you want to do game hosting..
