Ok this is interesting, 1 having a problem is OK, 1, 2 having it, still a low number , but adds credence to the first to not being for that specific setup.
Now, what is in common between 1 & 2. And could be the problem for 1 & 2?
I have a bunch of GW100Os and GW1100, but I don't have any reporting to WU, which seems to be entire issue area.
We kind of know that WU did some work on their stuff around October 20 something , I forget the exact date but that is when they dropped the web cameras. I am not for an instant saying that is the cause or related to the cause. Just strikes me as something to look at as , as , I believe , this started happening a few weeks ago for those affected approximate to the timeline. Possible other things were done?. No idea.
I do know my data to WU doesn't show the issue, but that is from WS-2000 console, which I send out at 16 sec intervals (I should recheck that , I may have changed it)
...Another thing, how many look at their graph data on WU? I can tell you I very rarely do. Maybe, this will encourage others to have a look, as the issues reported are short duration, you might not notice if not looking at the graph data.
