[time-nuts] Dumb Cs beam question: mechanical shock sensitivity?

[Christopher Hoover]

Should I expect a healthy Cs beam standard to lose lock if the unit gets
a sharp (enough) mechanical shock?  I'm just asking about the general
nature -- obviously implementations will have differing mechanisms for
and degrees of isolation.
 
My FTS 4050 lost lock briefly once when I was dropped another piece of
gear I was loading above it in the same rack.  The two events were
directly correlated.  I wasn't terribly suprised, but wasn't sure if
that was "normal."
 
It lost lock briefly last night, again, but for unknown reasons.  We did
have a small'ish earthquake, so I'm told ....

p.s. Look out for some questions on how to deal with outliers and gaps
in datasets for stability analysis .... I'll pursue the literature
first; pointers to anything of particular merit would be welcomed
kindly.
