Yeah, this was caused by Bind being rather silly when one uses views +
notifies. We have 2 views; your notify arrived in the trusted view
(because it originated from one of our IPs), and that view actually did
get updated, and sent out notifies to the other nameservers which
updated properly.

Turns out Bind does not also update the cached zone file in the other
views without some extra configuration to make the trusted view notify
the other view... Sigh, this is *so* much simpler with djbdns. Anyway,
it's fixed now.
