Darnit, it somehow thought I unsubscribe and stoped accepting my posts, so
I've subscribed again, and am trying this again.

First, the stale record is from the .net name servers (which are the root
nameservers), that record that delegates nakos.net to ns1.pbi.net. has expired
and should be refreshed from where it came from.

ns1.pbi.net is only authoritative for nakos.net by delegation from the .net
servers, and this should be honored.

Secondly, every other server on the net I can find has the new addresses,
leading me to believe there is some sort of configuration or something I've
missed - why is it only USC's servers continue to get the old data?
