DNS servers not picking up delegation change

Hi Euan,

DNS doesn't work like that - you have to ensure you put the
right data out, and then the rest will pick it up in the time
scale you arrange by setting the TTL.

The delegations look correct!

All the servers I have to hand have the new data.

Can you give an examples of recursive servers that have not
picked up the right delegation?

My guess if any problems remain it might be network overload as
all the servers appear to be on the same network.
