Which companies have run the Channel 3 services in the Divis transmitter area
The issue has resolved now after several days. It was not working this morning and now later in the morning, all the channels on that mux are back (after communicating with various people last night and early this morning). You say that problematic connections, water ingress, etc., can seem to affect reception of just an individual mux. This is interesting and I will check for these things.

To get more technical, problematic connections etc. can result in what's called standing waves in the cable which are often frequency specific and so affecting one particular frequency more than others.
Major cable breaks will of course have an effect on all signals.
This is why it's a good idea to make a note of the signal strengths and quality of signals for all the multiplexes when your system has no faults, then when there's a problem it can help to identify to possible causes.
