Read again, and note the word "us". I am describing my and my
employer's experience with past DST changes and leap years, and those
have indeed been completely uneventful.

YMMV.

As above, I am speaking only about how the 2012 leap second went down
in our infrastructure. I stand by how I described the event.

Again, YMMV. If you plan on let your infrastructure deal with the
upcoming leap second head-on, I wish you the best of luck. Hopefully
all the bugs from 2012 have been fixed. I, however, certainly have no
intention of being the one to find out otherwise.
