The Large Hadron Collider (LHC) was first activated in 2008 (see http://lhc-milestones.web.cern.ch/LHC-Milestones/year2008-en.html ) and ran for just over a week before a severe incident shut it down. The incident occurred when an imperfect solder joint failed, causing an explosive cryogen leak.
Following an extended shut down for repairs, the LHC was restarted in late 2009 (see http://public.web.cern.ch/press/pressreleases/Releases2009/PR02.09E.html ), though at significantly lower energies and luminosities than initially planned. You can read a surprisingly detailed and accurate article about LHC, what it's about, the incident that shut it down temporarily, and much more at http://www.vanityfair.com/culture/features/2010/01/hadron-collider-201001 .
The beam energy is expected to be brought back up to the spec 7 TeV on 7 TeV sometime in 2010 (see http://www.math.columbia.edu/~woit/wordpress/?p=2591 ).
