An incident happened at LHC while operations were in course to reach 5 TeV aim. You can read here and read Jester’s blog for other links and comments.
This will imply some delays in the initial optimistic schedule.
Update: The question is rather serious. News talk of about two months delay with respect to scheduled program. I have found another article about on New York Times.
Further update: CERN press release is here.
