My server isn't hosted by a Game Server Provider, my server is in a data center with very good Internet connections. I'm a professional Server Administrator (*nix and Windows), so I guess a Professional Provider with a Professional Server Admin might meet your criteria.
Name: The Way of the BAWK
Other Info: Hosting facilities from RackMounted.Com
, see their network description here
. Yes, that's a shameless plug for a company that has treated me pretty damn good for 2 years. I get good pings from DruidChiken (in Wales, UK) and SmuttyChiken (New South Wales, Australia), and from most places in between, like from KazakChiken (Greece).
The server IP will change, as I have a much beefier machine I need to find a home for that is near me, and RackMounted's facilities aren't local for me.
Edit: Spelling and adding server slots.
