For example, the BIND company has admitted that the
``zone coherency'' rule is violated by BIND 9.
Dan, 1034 itself says that absolute consistency is a non-goal. From 2.3:
Access to information is more critical than instantaneous
updates or guarantees of consistency. Hence the update
process allows updates to percolate out through the users of
the domain system rather than guaranteeing that all copies are
simultaneously updated.
