There is an interesting facet in your stats. It seems the upstream may be glitching. Your US-1 is on a frequency of 60MHz which means that VM have claimed some spectrum no longer used by analogue TV. Yet the higher frequency which is less noise sensitive than your lower frequency US-2 ismodulating at a higher packing density than US-1. The T4 timeout is a clue that the upstream may have glitched.

If that was a one off and it's all settlked down - then fine. But keep an eye on the upstream if it happens again.
