Server Fault is a new Q&A website for system administrators and IT professionals, brought to us by the folks who brought us Stack Overflow.
It just started its private beta, which is open to any Stack Overflow user with a reputation score of 100 or higher, or anyone with an OpenID who submits a request. See the Stack Overflow blog entry for details.
I'm in the process of setting up an Ubuntu web server on a Xen VPS, so I expect to have a lot of questions to post on Server Fault. It arrived at the perfect time.
