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?
This bad service is by design, and required the following standards to be set a) Never work with your competitors in a way that makes changes to the DNS seamless b) Always have at least 7 days TTL in your zone files c) When loosing delegation, remove the domain from your authoritative name servers instantly Its not about name servers updating records. Its about them forgetting what they last knew to be useful data. Unfortunately, they remember it for a period of time set by whoever provided that data in the first place. Unless you are really clueless and have authoritative name servers that allow recursion and you encourage your customers to do lookups on them. That way you serve them stale data until somebody or thing removes the domain allowing the new world view to appear.
