NTP Issues Today

Tue Nov 20 03:28:06 UTC 2012

crossreplying to outages list.

Is anyone ELSE seeing GPS issues?  This could well have been an
unrelated issue on that particular PBX.

If this was real, then the mother of all infrastructure attacks might
be underway...

One glitch on tick and tock and one malfunctioning PBX is not
sufficient evidence of pattern - much less hostile activity - to
induce panic, but it would perhaps be a wise time to check
time-related logs?
