mmmm... not sure what you are referring to, can you be more specific? We have not changed the way we measure pageviews for 2 years

There are improvements/fixes continously done to the system and those get documented here:

https://meta.wikimedia.org/wiki/Research:Page_view#Change_log


FYI, we have opened a ticket for this issue: https://phabricator.wikimedia.org/T170845

Without looking at it in detail there are many possible causes: removal of "bad" pageviews (like requests for banners) or drop of traffic due to having less bots.

Thank you Igal, that must be the reason, I'll look for the change
announcement just to understand what it means exactly.
