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.
