All is not well, though

* National Physical Laboratory is still advertising the leap second

$ date; ntpq -c "mrv &1 &999 leap,srcadr,stratum"

Wed 1 Jul 15:07:44 BST 2015

srcadr=139.143.5.31, leap=01, stratum=2

$ host ntp2.npl.co.uk

ntpsvr2.npl.co.uk has address 139.143.5.31

* A large number of servers didn't, list of servers by country code:

* Google servers (time[1-4].google.com) didn't advertise the leap second, and slewed rather than stepped for the 12 hours before and after, (which was exactly by Google's design).

(Also an interesting "discussion" on systemd's use of them by default)

* And one server didn't advertise it, was OK for a while after 00:00:00 UTC, and is now about a second out

-ntp0.ovh.net .GPS. 1 u 337 1024 373 2.691 997.187 920.966

Probably due to an issue with its GPS interface
