There is a currently private beta site for Network Engineering here:

http://area51.stackexchange.com/proposals/52519/network-engineering

The beta is new, but seems to be garnering a decent following so far, and will probably ramp up participation when it becomes a public beta site. I think this new site should exist...as this is a core role/area within IT.

Given that the ServerFault FAQs state that a question can be about:

Network routing, switches, and firewalls

and the site name is Server fault...is the idea to get back to a core based on the name of the site, centering around questions regarding server administration and moving networking questions to their own site, eliminating this from the FAQs and acceptable topics?

If so, what happens when these questions overlap (ie. serverA cannot communicate with serverB)?
