What do you mean by server? Web hosting?
If you mean ISP, then the best rated DSL is Atlantic Nexus. I have it and it is rock solid and faster than ATT. Can do 6mbps residential or 12mbps biz class.
Can't help with cable. You will have to see what is in your area (probably only one choice.) It is useless in my neighborhood.--
