Image tarball dumps were being generated at http://ftpmirror.your.org/ on a somewhat monthly basis from April 2012 - December 2012. The last complete set
was in December 2012 . A January 2013 post  indicated a hardware issue at your.org. A July 2013 post  indicated that the hardware issue was resolved at your.org, but further progress required a new setup due to the recent Wikimedia datacenter move.
