BU seemed busy this morning - check the wall of shame thread. I don't know about other schools. Today seems like an odd choice to send out rejections.
Oh, and my deepest condolences. This is a disappointment, as much for those who are responsible for the decision as it may be for you, the candidate who is turned away.
I acknowledge and respect your accomplishments, and recognize that Boston University's inability to offer you an opportunity to complete the admissions process is a loss for Boston University. Please accept my best wishes for all your future endeavors. Or something.
