• What are the observed vs expected results? Please include information such as location of data, any initial assessments, sql statements, screenshots.

Starting Tuesday Jan 9th the nl.wiktionary user pageview count per day suddenly is nearly double the usual level. At the same time the ratio of those pageviews to unique devices grew from a little more than 2 to around 3. This sudden growth is only visible in the pageviews from desktops, pageviews from mobile are in a normal range. We have had peaks like this in the past for a few days, but by now the increase has been lasting for nearly two weeks.

Of course, we would be very happy if a small group of deeply interested desktop users suddenly has discovered us. However, before we start ordering the celebratory stroopwafels, I'd like to know whether we might be witnessing the birth of some kind of automated use you are not presently detecting?

I would be grateful if you could shine some light on this matter.

Thanks in advance!
