Speaking of NTP...

We have 5 NTP server:  2 x stratum 1 rubidium oscillator time servers with GPS sync, and 3 servers running NTP 
4.2.6p5-3 synced to external internet based NTP stratum 1 servers. We monitor our NTP environment closely, and over the 
last 10+ years, normally all of our NTP servers are sync'ed within +/- 2 msec. Starting last Friday, we started seeing 
some remote NTP servers with GPS reference consistently offset by 10 msec. 

Any one else seeing this?
