I said when I rode on Sunday that it probably wouldn't last a week, by the end of the cycle I'd revised my guess to 2 days. In the end it closed within a few hours. I wouldn't be surprised if it's closed for an extended period yet again - they need to sort whatever the underlying issues are.
Since this thread is also for ride operations, I was generally fairly impressed with the ride operations on Sunday - particularly on Oblivion (which was chucking out the shuttles at a rate I've not seen in years), Thirteen (which was achieving dispatch times rarely seen since 2010) and Spinball (which was probably beating some of the bigger coasters for throughput). Sadly at the other end of the scale Galactica really seems to struggle these days. Not sure if it's on reduced staffing compared to previous years or if it's just due to the restraint sensors becoming less reliable but they really seemed to be struggling to get the trains out in a timely manner. Back in the day they'd routinely be dispatching when the previous train went through the lie-to-fly but nowadays stacking seems fairly common.
