Wikimedia releases anonymous search log files for Wikipedia (thenextweb.com)

AOL and Netflix have been bitten by the deanonymization of their search/recommendation logs before. What will keep the same from happening here?

http://dumps.wikimedia.org/other/search/ is the direct link. Will be interesting to do some compression tests with these files - I think Wikimedia could save quite a bit of bandwidth by using LZMA or similar.

Does anyone have a mirror? Link seems to be empty.
