Patch notes would be helpful. It helps the developers as well as the users. We can't give any useful feedback if we don't know what was supposed to be changed/fixed/improved.
No patch notes just leads to duplicate bug reports about things that were not intended to be fixed, bug reports about things that work correctly but we don't know that it was an intended change and no bug reports about things that were intended to be fixed but weren't.
Also, rotating when these down time occur would really help. I get sick of being the same time every day when I have a few hours to play.
