No, the bugfix makes those faulty requests to no longer be stored as pageviews thus it cannot make that number increase. I am not sure we can link the surge of "-" pageviews in October to any determined cause without further research. Have filed ticket to that extent, hopefully we can get to it before we do away with raw data: https://phabricator.wikimedia.org/T150990 >And, does that means that the current estimate of "-" pageviews is more accurate than it used to be prior to the bug fix? No, it doesn't. On Thu, Nov 17, 2016 at 1:17 PM, Vipul Naik <vipulna...@gmail.com> wrote: > Thank you for linking to that bug, Marcel.
