> RF problem or not, how would you track down this problem? 

To start with I would install some cheap equipment that
is more likely to fail so that you can INCREASE your
failure rate and get some more data. Maybe consumer grade
DSL switch/routers or something like that. Also, talk to
radio experts (ham radio) about how to measure the field
strength. It is entirely possible that there is some kind
of accidental waveguide that channels RF into your facility
under the right conditions. Grounding could also be a problem
if somebody is pumping lots of volts into the ground nearby.

By the way, your timetable sounds like a factory source.
Something is done on every shift change, and then maintenance
does it once more during the night shift.
