Yahoo Fantasy System Down During the Day!!

The one time I go to check my fantasy teams during the day I get this!!

Who does performance maintenance during the day? Being a IT guy, I have never heard of a big company doing a “scheduled site upgrade” during the day. These are always done at night unless it is an emergency and you have to bring the system down during the day. Way to waste my time and not let me prepare my few remaining fantasy football teams for the playoffs!
