Sorry for this code scheme being not so intuitive, which two meanings for 'm' depending on where it appears. The coding system was extended several times, and Christian Aistleitner and I prioritized downward compatibility over intuitiveness, reluctantly.

Yes, the ".m" code can stand for either being a *.mediawiki.org <http://mediawiki.org> project or for being a mobile wiki (you can separate both cases). See the docs here: https://wikitech.wikimedia.org/wiki/Analytics/Archive/Data/Pagecounts-all-s… I created a task to add some more documentation to the page you linked: https://phabricator.wikimedia.org/T180452 Thanks a lot!

However, I've been coming across a large number of wiki codes "en.m". The "m" code is undocumented. It appears to be the mobile version of Wikipedia, but can anyone confirm that? Should the page be updated with this information?

Thanks, Federico. In the docs you referenced, I can't find any reference to "en.m" that contrasts with the "en.z". This page <https://archive.org/details/wikipedia_visitor_stats&tab=about> describes codes, but they're different from the ones in pagecounts-ez <https://dumps.wikimedia.org/other/pagecounts-ez/>. I've noticed the "en.m" lines only started appearing in Dec 2015. I'm just trying to understand, if I want the most accurate pagecounts over time, should I be including the "en.m" lines on top of "en.z", or are they something different?
