St3fan's Server Hosting is the best one in the world. Where do I begin?
First of all they are cheap. Really really cheap.
Secondly they have exellent Ping and Connection. If you are lagging while being on the server, I can promise you, its Your fault
Thirdly, but maybe the best of it, Stefan will always be there to help you. I have annoyed him several times when I want him to either change adminpass, put in a New map, unbann/bann anyone. And he always does it. In my years on internett I have not seen but a few that are more honest and caring guy like Stefan.
So if you want to buy a Warband Server, does it here. Do it, you won't regret it.
