The European Organization for Nuclear Research (CERN), who launched the Large Hadron Collider in October 2008 is leaking data... After being forced to shut-down the huge particle collider, due to various technical problems, it looks like they're having some IT issues too...

That's what a simple Google request looking for SQL statements is resulting in. By displaying of mysql-backups hosted on a CERN machine, it seems that a big collection of data is publicly available.

Edit (2009-02-09): It has finally been fixed, a joyful 403 error is displayed on http://iepmbw.cern.ch/iepm-bw.cern.ch/mysql-backup/ but, currently, the parent directory still provides "Index of" files.

Edit (2009-June): It has finally been completely fixed, host is down!.
