A bunch of companies can't be bothered to figure out how to avoid
obvious single points of failure in their DNS administration.

   $dig -t ns tourcorp.com +short
   ns1.primarydns.com.
   ns2.primarydns.com.
   $dig ns1.primarydns.com +short
   216.219.239.7
   $dig ns2.primarydns.com +short
   216.219.239.8
   $

   $dig -t ns mapwest.com +short
   ns1.primarydns.com.
   ns2.primarydns.com.
   $

   $dig -t ns sfelectrictour.com +short
   ns1.primarydns.com.
   ns2.primarydns.com.
   $

Bonehead error.

Cached data.


One wonders if these the same people who run Six Apart (parent of Live 
Journal), or if this is merely an instance of parallel devolution.

   $dig ns1.sixapart.com +short
   204.9.178.9
   $dig ns2.sixapart.com +short
   204.9.178.75
   $

   $dig -t ns livejournal.com +short
   ns1.sixapart.com.
   ns2.sixapart.com.
   $

he turn their ankles so we'll know them by their limping.
