+    ns02 is a master dns server. 
+    It serves about every domain under fedoraproject, fedo*, as well as others, both forward and reverse. 
+
+    * This host relies on:
+    - The virthost it's hosted on (ibiblio03.fedoraproject.org)
+    - batcave for dns git and keys
+    - connectivity to maxmind to create geoIP dns acl
+    
+    * Things that rely on this host:
+    - The Internet/Community to resolve everything related to fedora and reverse-IP for allocated subnets
+    - If this host is down, dns queries will slow down by the portion of this host to the total name servers responsible for the same domain set.
+    - secodary/slave dns servers
