You're gonna love this
we've been trying to pin it on the carrier for a while
latest rumour is that the radio bearer (rather transmitted waves)
at the central site gets 'radio fade' during high tides
the thing you don't see when you're not at site
hence the intermittant nature... now if I can just correlate the tides with the
flapping

Looked at serial interface usage, I mean is it dropping during periods of
peak utilization?
