First there was a glitch with one of the huge 30-tonne transformers causing a delay of a few days, then a quench leaked a tonne of helium coolant into one of the tunnels, forcing a two-month shutdown while repairs could be made.
Brace yourselves for some more bad news.
In a statement released by CERN today, due to an obligatory maintenance period, the LHC will have to remain off-line until late March or early April 2009. Problems with an experiment as huge as the worlds biggest particle accelerator can be expected, but this will be a costly delay and a psychological setback after the initial excitement of the first particle circulation on October 10th. The elusive Higgs Boson will have to wait a few more months...

Noooo! I knew it would be suspended for ~2 months when I heard it had a small electrical problem, but now this?

Not a small electrical problem. There was a helium leak, and they have to correct a problem with the magnets. They have to be at 2 Kelvin, but they're at 4 Kelvin (four degrees above the coldest possible temperature, which can't actually be reached). They need to be heated up to room temperature (~294 Kelvin), repaired, and then cooled down. The warming and recooling processes will take a long time.

Ah, the crappy media lies* to me again. I heard the problem was an electrical problem, rather than a helium leak. It was correct on the temperature matter, though.
