[AusNOG] Telstra DNS contact

I had a similar problem when I was using Telstra for a secondary. Their 
recursors apparently lookup their authorative (and secondary) first when 
answering a query. They favour resources on their network first before 
going external (which is logical). I had probs redelegating (luckily I was 
running the old config in parallel so there was no impact). I was not sure 
if my TTL or Expiry was too long or what, but the problem cleared itself 
up a week later.

Regards,
Heinz N. (Without an AS)
