I believe so. Looking at their site and reading their testimonials, I believe Liquid Web is a good company to be with. And there is no complaints on WHT about this company so you shouldn't worry to get a dedicated server from them.
If you want a managed server, they are very, very good. I am surprised you can't find info on them in wht. I see posts all the time praising them.
I have one machine there and they have always been extremely polite when I have called. They answer quickly (try calling their support number as a test). All of my tickets have been quickly and thoroughly dealt with.
I would highly recommend them (although I usually try to keep it a secret so they don't get TOO busy, if you know what i mean ;-)
I find it hard to believe you can't manage to find any good recommendations for them, quite a few happy customers of theirs have posted numerous times. For managed dedicated companies on WHT, they'd be in my Top 5. Got to give credit where it's due.
