What happened to XLC?

Hi everybody! (Hi Dr. Nick!) I don't live particularly close to King's Dominion, but since we are planning to go there in August or September, I went to the website. It said "HyperSonic XLC returns to service!" I was just wondering: what happened to it to cause it to be out of service?

And how long was it out of service? I had heard about it's (lack of) reliability, but taken out of service...that's news to me.
