It's most likely just a much needed refurb. Having been open for 2 years, it may not have had an extensive shut down, cleaning, and maintenance. Since we in Orlando are in the off period (at least until early December) several rides start doing their annual full maintenance around now. Probably will only be down for a few weeks, sorry you didn't get to ride.
