wow what a great deal! the page is down!!
anyway, i am pretty happy with dixiesys. I got in on a few "2 for 1" deals and am currently paying $10/month for 800MB space and 15GB bandwidth. I recently moved to a DA server from an Ensim server, and the only problem I had was backing up my phpBB2 database.
It seems like they are slow to respond to helpdesk tickets sometimes though, and sometimes all they do is link you to a forum post (usually that i've already seen, i don't do helpdesk tickets unless i search the support forums first).
Another example is that I was having trouble sending email all of a sudden, their response was to move to a new server. I moved to a new server, still had the problems. Turns out my ISP was blocking port 25, they said "call your ISP and see if they can fix it"
they couldn't, so i asked if port 2525 would work and never got a response. I found a very old forum post with that info in it, so when I got home and tried it, it worked. I went ahead and closed the ticket myself after that.
