Temporary increase in main ping submissions

[Mark Reid]

Hi all,

I spent some time investigating this problem today, and came up with a
couple of data points.

1. There was a large increase in submissions from the ESR channel at around
the same time, which Peter was kind enough to help me track down to the
work in https://bugzilla.mozilla.org/show_bug.cgi?id=1318922 .
Unfortunately, if I filter out submissions from ESR, the spike still
appears plain as ever, so this is not the explanation for the increase.

2. There was also an increase in submissions where the "reason" field is
set to "environment-change". These submissions *do* seem to correlate very
strongly with the observed spike, and are my leading hypothesis for the
explanation. So far I don't have any good explanation of why there was an
increase in this type of ping.

If you are interested in the analysis behind the above, let me know and
I'll send you the jupyter notebook. It contains some client counts and so I
can't make it public without scrubbing it (which I plan to do in due
course).

Again, if you have any suggestions for directions to take for further
investigation, I'm happy to hear them.

Thanks

Mark
