Arnaud posted about CPS glitches in the CPS HAM5.  Though it prudent to scan LHO for similar.

I looked over the past three weeks and found none that were shaped like LLO (very narrow spikes to near 40k counts.)  WHAM6 had some associated with the fast shutter although I did not establish cause/effect there.

WHAMs 2 3 4 & 5 all had one exceeding 20k counts at the same time 0030 utc 30 March but was not a single spike, looks more like an Earthquake.  Bottom line, we should be ever vigilent but for now, LHOs HAM CPSs are not glitching.
