Seth, My point exactly. Use GPS as primary, and have anti-PS back up, and if you want automatic fail over, do that in an intermediate server on your site that makes a conscious test and decision to fail over to regular NTP -mel via cell

These are spread across four different locations in two different states. My understanding is that they all get their time directly from the official NIST clocks without GPS or NTP being involved.I used to jump through all the hoops for that but honestly I like the appliances better (they are also PTP grandmaster clocks). I can always disable the GPS inputs if any of the doom and gloom actually comes to pass. ~Seth
