DNS zones update according to the settings in the zone.  Resolvers LOOK at this and work out how long to cache.

(I've been explaining this for about 15 years now - it hasn't changed).

If you're making changes to your DNS zone then you need to understand which of the timer settings in your zone to alter and when in order to get the behaviour you want.

Lately I've had a lot of issues with domain nameserver changes taking ages to propagate in NZ.
They seem to propogate really quickly everywhere else in the world from what i can tell.

Do some NZ ISP's take longer to update their DNS records for some reason?
Anyone else experienced this?
