While my colleague is working with a stratum 1 timekeeper to investigate
this better, I called the people at INRiM in Italy -- INRiM is the
institution responsible for the official Italian time
(http://www.inrim.it/index.shtml). Mr.Pettiti confirmed there was *no*
leap second scheduled yesterday (as we all suspected, right?), so that
is definitely a fake.
It may well be a DOS attempt, but as another colleague of mine suggests,
it could also be a bug in some upstream servers, which didn't disarm the
leap second after June 30th, and propagated it again yesterday.
Question now is: assuming those servers were running ntpd, was such a
bug reported at some point?
