No. The master is the blind primary on the 62.65 network, hasn't
changed. And I see you transferring from there.

That, however, is wrong. I don't know why neptune is sending out
notifies - it's not the master. It's not even a slave for that zone!

Also, I ran my test script. Seems there are problems with several of the
listed nameservers!

We have the following servers:
ns.hub.org | 200.46.204.2
ns2.hub.org | 66.98.250.36
ns3.hub.org | 200.46.204.4
ns-a.lerctr.org | 192.147.25.11
ns-b.lerctr.org | 192.147.25.45
ns1.pgadmin.org | 194.217.48.34
ns2.pgadmin.org | 81.187.210.23

Of these we have:
ns1.pgadmin.org and ns2.pgadmin.org - don't resolve at all. Changed or
should be removed?

ns.hub.org - now has a different IP? But something is answering on the
listed one? And it's the old one that sends notifies? Which one is
right?

ns3.hub.org - now has a different IP? Nothing answering on specified IP.

This means that more than half the DNS servers have changed since this
system was set up (and that was just a year ago! DNS servers are
supposed to be stable :P), and not one of the changes were reported
here... (Or if they were, nobody made sure the system was updated. But
I'm fairly certain I haven't heard anything about it)

Anyway. If I can get confirmation on how the above is supposed to be,
I'll fix it up ASAP.
