We have one dedicated server right now, but are about to upgrade and get a 2nd more powerful server. We're on a P4 right now w/ 1GB RAM at EV1 and are upgrading to a dual-xeon 3.2 with 2 GB RAM and RAID.
I have 3 dedicated servers at godaddy. 2 at 1&1, and 2 at ThePlanet. They're all managed but one with 1&1 that is not. Having so many servers is a pain for me, too much going on, specially taking into consideration that I know very little about servers and managing them. Most of the time, for updates and cron jobs and backups, and optimization and such I have a guy that does all this for me.. How many of you use service administrators, and how many manage your server by yourselves?
