Just had a lovely one.

As I'm, sure all of you are aware by now, there's been much fun with some of the NTP Stratum 1 servers not correctly accounting for the leap-seocnd last night.

You may wish to turn off ntp on your servers and correct your NTP to trusted servers.
A clock skew from ntp.pool.org just took out one of our servers and the node was expelled from the cluster.
