Such delays can be reduced by proper pre-planning of changes.  When
changes to all or part of a domain are expected, change the TTL [Time To
Live] of existing records to some short period (such as 900 seconds) at
least a WEEK before making the change.  After this reduced period has
propagated world-wide, other servers attempting to collect the
information will know that it is more ephemeral, and will collect it
more often and/or sooner.

Then make the changes; wait 30 or so minutes for them to propagate and to
check that everything is working as desired, and then put the TTL back to
the usual 3--7 days.
