It looks to me that Your domain (Source.com) could not be resolved at the time.
It seems to work now, so i assume you have temporarily problems.

BTW both NS for source.com seems to be on the same LAN and thus can be 
isolated from internet by a single cause. Most people recommends
that nameservers should be in differnt parts of internet.

;; AUTHORITY RECORDS:
source.com.     86400   NS      ns.waymark.net.
source.com.     86400   NS      ns1.waymark.net.
;; ADDITIONAL RECORDS:
ns.waymark.net. 86400   A       207.18.144.2
ns1.waymark.net.        86400   A       207.18.144.4
