A problem occurs, maybe on Saturday evening? No matter, the fri... Više endly staff is always reachable and they always find quick and professional solutions for you.
What I really like is the way of communication, it's very personal. You can easily contact the owner(s) of this company and I personally do always have very nice and interesting talks with them when I am at the datacenter for my colocation services.
Also the other services XSServer is offering do have a great level of quality, no matter if dedicated servers, VPS or other services like domains. Manje
