This area is finished about 1-2 months ago I think (sure I have seen some of the 8 ports been used recently) not so much H&S more snapping the fibre killing 8-16 houses or more if its additional feeder to another pole nearby that is an extension Pole
M J Quinn contractors does sound about right who did it
