I'm happy to announce a new mirror for datasets other than the XML dumps.
This mirror comes to us courtesy of the Center for Research Computing,
University of Notre Dame, and covers everything "other"  which includes
such goodies as Wikidata entity dumps, pageview counts, titles of all files
on each wiki (daily), titles of all articles of each wiki (daily), and the
so-called "adds-changes" dumps, among other things. You can access it at
http://wikimedia.crc.nd.edu/other/ so please do!
