Name servers propagation
Discussion
Overthr last 18 months, the time it takes for changes to bits of information suh as nmeservers has reduced massively from 24 hours down to a change I made last night resulting in an almost instantaneous change.
The domain I was working on at the time is in the USA so it can't be because it is local here.
Does anyone have any idea as to why/how...???

P. S. I'm not complaining, just interested!!

DNS is a caching system, this affects how changes propogate.
New A record should be instant as it wont be cached anywhere so will trigger lookups to the authoritative servers.
Modifying an existing record will depend what the refresh interval is set to in the SOA record. If it's three days then you might have a long wait for your change to propogate to the whole interweb.
I recommend reading DNS and BIND published by O'Reilly.
