 It seems deeper than that, though.
 
 If you query one of the other authoritative DNS server you get the  
 CNAME for cvsup11:
 
 ;; ANSWER SECTION:
 cvsup11.freebsd.org.    3600    IN      CNAME   freebsd- 
 mirror0.research.uu.net.
 
 and looking that up, you get no answer for the A record.  So if you  
 query any of the NS records for uu.net, you get referred to other NS  
 servers for research.uu.net, and no answer to the A record:
 
 ;; AUTHORITY SECTION:
 research.uu.net.        3600    IN      NS      beast.research.uu.net.
 research.uu.net.        3600    IN      NS      auth03.ns.uu.net.
 research.uu.net.        3600    IN      NS      auth50.ns.uu.net.
 
 ;; ADDITIONAL SECTION:
 beast.research.uu.net.  3600    IN      A       63.87.62.73
 
 Querying the auth* hosts you get the same answer back; querying  
 beast.research.uu.net I get no response:
 
 
 % dig freebsd-mirror0.research.uu.net @beast.research.uu.net
 dig: couldn't get address for 'beast.research.uu.net': not found
 
 and even:
 
 
 % dig freebsd-mirror0.research.uu.net @63.87.62.73
 
 ; <<>> DiG 9.3.2-P1 <<>> freebsd-mirror0.research.uu.net @63.87.62.73
 ; (1 server found)
 ;; global options:  printcmd
 ;; connection timed out; no servers could be reached
 
 
 so something is *really* wrong I think.  Normally these  
 research.uu.net servers are just 5ms from me and I believe they're in  
 the same data center.
