	The propagation really depends on TTL. Normally this is set to
24hrs (may 
	be different), so while some NSs update quicker, some don't feel
the need 
	to update unless the record expires.

Now we are getting to the real point! Some servers don't bother checking
till the TTL runs outs. And now the issue is that some DNS have even
just dropped the domain all together which means it can't be a TTL
issue.

If all the Nameservers were setup as the RFC then we would have 1/2 the
probs we do. Sometime you toss up making the TTL sort just to solve the
prob but that has issues of it's own.

It has only been this bad since the Change over to the new system and
now people like Connect and Telsta are not primaries for .au like they
used to be.

Anyway! Griping is not getting it solved!

Thanks
