Human nature. When everything's going fine no one really notices or says anything. One screwup and it seems like no one will shut up about it or forget it. Anyone who's ever held pretty much any job anywhere should be well aware of this phenomenon.
As, I guess, the chief complainer since I posted this, I was not technically complaining but simply reporting a problem. I did finally get back on today and expressed my many thanks for whatever they did to fix this.
