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" [1] 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!
