  ftp.cisco.com name server rtp5-dirty-ddir.cisco.com
  ftp.cisco.com name server sjce-dirty-ddir.cisco.com

Look at the query time. The other NS for ftp.cisco.com has a similar
time for me. I didn't show it here, but the NS records for ftp.cisco.com
have a 10s TTL too. And look at the name of the servers. Odd. Not exactly
sure what's going on down the street with them.

Load balanced nameservers.  I assume these are all being DDoS'd as well, so
that the actual nameservers behind the hardware (cisco?) load balancer are
overloaded.
