Long time reader first time writer…

I've exhausted my search for refid .FLY. and its meaning.

Our stratum 2 client reported Stratum 1 172.17.172.74 appliance (Symmetricon S200) initialized with .GPS. but after ~ 24 hours the refid switched to .FLY. and the offset has been steadily increasing.

Any guidance to what this means appreciated.
