Here is one that I'm working on (not quite official) - the official one
will be on arin-announce.

On March 19, ARIN performed a fork-lift upgrade on its database and
provisioning system. The first set of zone files generated and published
on March 20 at approximately 2:00AM EST omitted placing name servers on a
number of non-customer maintainable zones (169.254/16, 172.16/12, and
192.168/16). While the nameservers continued to display in ARIN's Whois
service, the zone file generation software was written such that
non-maintainable zones weren't actually written to the zone files. ARIN
was notified of this omission in the evening of April 9 and was fixed the
zone release on April 10. The zone release on April 10  was visible at
approximately 10:00PM EDT. We apologize of any inconvience that this may
have caused.
