The most important functionality that I find useful for is the ability to see the performance of the servers. The interface is very simple to use and I find that the speed of the servers available is very good. I also find that the price of the servers is very fair, considering that the servers have a lot of performance and the service is very good. I have not find much I don’t like about the vCitadel service. I have not use all the functionality that the vCitadel service offers. I’m currently in the process of creating a server for a website that I’m creating. I use the servers to host images, the CSS and the web server. I use the vCitadel web server for the images and the CSS. Easy access, easy management - no need more complex tools like other providers have (eg Zend). Good support by phone or chat as well! Nothing really specific that I would dislike about it so far but maybe some features are not available yet? We're using them mainly because we want our own hosting provider with lotsa control over everything including server configuration etc which can be managed easily from their platform too if needed/wanted.
