I'm sorry, but you're mistaken. Quoting Server Fault's What is on-topic:
What topics can I ask about here?
Server Fault is a site for system and network administrators needing expert answers related to managing computer systems in a professional capacity.
If your question is about…
- Network routing, switches, and firewalls
We have significant overlap with Server Fault. It's part of Stack Exchange... we're a focused group of network engineers with no other "noise". They have network engineers mixed in with system administrators and jacks-of-all trades.
Also consider how much overlap there is for linux topics...
