Thread:Project:Support desk/Download link to MW 1.15 legacy on download page dead/reply (2)

This is a known issue, the download server is temporarily down. You can get the latest version (1.16) at http://noc.wikimedia.org/mediawiki-1.16.0.tar.gz. I'm not aware of any mirrors of the older versions like 1.15. If you _really_ need it I suppose you could download it from svn.
