I'm guessing they will not be up at midnight pacific time. On the other hand, I do wonder if the patch is completed and the technicians are sticking with their original ETA? You have to imagine 24 hours is not the exact amount of time they needed to finish maint. I'm sure they gave themselves some leeway. It would be smart to catch us by surprise rather then flip the switch at 0:00 pst. Authentication servers will have a difficult time with everyone logging in at once. Lets keep our fingers crossed....
