Yes, and propagate means to have offspring or to be something
tangible that grows or moves.  DNS records don't do either of
those things.  Promulgate is the word for the spread of the
awareness of an intangible item, such as a law or a DNS record.

Incidentally, the reason so many places say it takes 24 hours to
promulgate is that Windows has a local cache where it keeps
records for 24 hours regardless of the ttl of the record.
