Maybe they forgot to shut it for Rosh Hashana, but we Jews had a 3-day straight Yom Tov holiday, so once Rosh Hashana began at sundown Wednesday night, none of us could turn our computers on until after Shabbat ended Saturday night, so whoever was in charge could not get in to shut it for Shabbat if it was already left open for Rosh Hashana. I think circumstances point to this being an accident. People get really busy right before the holidays, especially a long one like this!
