Do you know how DNS works? Slaves don't just ask for a transfer willy-
nilly. Slaves are known to the primary and they get told when to ask.
I'm not sure this is correct. We should investigate before insulting
each other's intelligence.
I know a great deal about how DNS works, thank you very much. ;)

I have no idea what you are talking about. This is not some huge DNS
service that we need. We need to serve exactly one zone. This can be
done from a Palm Pilot, to be honest. I have run DNS services for
years and years and don't share any of your doubts.
Okay, let's please not make this an argument.
*we* do not have large-scale DNS needs.
However, if we use someone like ZoneEdit.com, their nameservers are
highly loaded. So, as I said, if someone decides to launch a DNS
attack on ns1.zoneedit.com or whatever, it can affect the availability
of zope.org, unless there are alternates, which is what we all
It's a sad logical fallacy for you to state that because you have
never seen this problem, it does not exist. I spent nearly three
years as an engineer at one of the world's largest provider of managed
internet services, and I can tell you that NS.RACKSPACE.COM and
NS2.RACKSPACE.COM are hit multiple times a year by 8MB/s or greater
