    This is rarely best.  In the common case, any specific piece of
software being installed has not changed in the past day (or even past
week), and so collecting from a nearby location (in terms of network
topology) is preferable.  If a set of packages must be up to date,
that repository should not be distributed in such a way as to allow
delays (e.g. security.ubuntu.com).  If an individual must have the
latest set of packages, adding a more frequently updated mirror as a
secondary source is a possible local solution, such that most packages
are taken from the local archive, and out-of-date packages are taken
from a more updated (but less close) archive.
