>Description:

DNS resolution related to cvsup11.freebsd.org may be broken.

Last worked by forward dns until at least:
 20060925T1900

The host and service is still there by ip address at:
 63.87.62.77 [aka: freebsd-mirror0.research.uu.net]

The mirror is up to date.

The nameservers for the following zones seem to be missing soa:
 research.uu.net.
 62.87.63.in-addr.arpa.

This nameserver seems to be offline:
 beast.research.uu.net.  1H IN A         63.87.62.73

cvsup11 has historically carried all the collections under
SNAP_16_1h with consistently good service.

Is anyone else seeing this, comments?

 ns1.downloadtech.com is causing the problem.

 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.

 Oh the joys of X mergers and Y rifs...  I have no idea why beast is
 unreachable or who manages it these days, I've reconf'd the zone to 
 run primary now, so it should reappear on auth03/auth50 in the next hour.

 no. cvsupx.freebsd.org are all cnames to some
 other fqdn that is not in freebsd.org. this
 is a perfectly good way to do it as it lets
 the host org move things around at will without
 coordinating such triviality with hub@.
 the freebsd.org nameservers are happily returning
 cname results [non-recursive] as per the extent of
 their programmed authority.
 
 as an aside, perhaps these should also use that format:
  cvsup2.us IN A 130.94.149.166
  cvsup7.us IN A 129.250.31.140
  cvsup3.pt IN A 193.136.165.121
 
 now back to the problem. when asked to recursively
 resolve the cvsup11 cname to an A record, or to do so
 via multiple finer grained queries... resolvers and
 nameservers [including freebsd.org. authoritative ones
 such as downloadtech if asked] will timeout because the
 uu.net records do not resolve as per the pr.
 
 the solution is any of:
  contact uu ;-]
  ignore it, cvsup to the ip, embrace uncertainty ;-[
  find another mirror as good as cvsup11 ;-|
 
 as for contacting uu, there's no historical reference
 to 'cvsup11|research\.uu\.net' in the entire mail
 archive so no help there. failing others, try
 hostmaster@uu.net as listed in the uu.net soa.
 
 if someone does contact uu, let them know that of the three
 authoritative servers for research.uu.net listed in uu.net,
 the two authxx ones below do not seem to be carrying its
 records either. so if they're just caches and beast goes
 away, ergo research after a while. uu.net zone is missing
 glue to beast.research as well.
 
 @auth00
 research.uu.net.        IN NS        beast.research.uu.net.
 research.uu.net.        IN NS        auth03.ns.uu.net.
 research.uu.net.        IN NS        auth50.ns.uu.net.
 
 the reverse part has been omitted.

 Is this issue at all related to the recent discussion of
 resolver failures for register.com (quite a large international
 registrar) due to a DDoS being distributed across numerous
 points in the AT&T network?
 
 See NANOG mailing list archives for details; thread is titled
 "register.com down sev0?"

 This PR should be closed.  The UUNET engineers have fixed the DNS
