First of all, I realize this is an old topic, but I just wanted to throw my two cents in on FDC, mainly because this post is number 3 in google when you search FDCServers
Haha, anyways, I used to use HiVelocity and switched to FDCServers because of the price mainly. I had a dedicated 10mbps connection with HiVelocity and it was located closer to me (West coast, and I'm West Coast) then my Chicago FDCServer. The FDC Server has a better response time and is a 10mbps Shared connection. Upgrading is cheaper in the long run; overall a better service... although I do miss the live chat; but they do have fast response and resolution times
Anyways, that's my 2 cents.
Cheers,
