From TPM:

Hackers broke into the email account of the George Mason University provost in Virginia, early this morning and sent out the following email:

Subject: Election Day Update To the Mason Community:

Please note that election day has been moved to November 5th. We apologize for any inconvenience this may cause you.

According to Dan Walsh, a spokesman for the university, the hoax message went to the entire student body — more than 30,000 students — and about 5000 faculty and staff.

Stearns himself quickly sent out a followup message assuring recipients that it was a hoax, which was being investigated.

Walsh said the university had contacted campus police, who are working with outside law enforcement to look into the hoax.
