Interesting, no matter what the explanation is (and I use Wachovia.) If it was a general emergency “test” message, it would probably announce it as a test, and it would not include a specific date. (Wachovia couldn’t run the risk of “all personnel” erroneously staying home on Nov. 1st because of a test message.)
I’m inclined to think it’s an old message, possibly from the Wells Fargo takeover, which took place in 2008. So the question is: did that transition happen on November 1st? If it wasn’t on the 1st, and if no other Wachovia emergency happened on Nov. 1st in the past, then this may well be a new message. Whatever it is, the message assumes Wachovia’s personnel already knows what the “emergency’ is about.
Nov 1st was likely the date of the last business continuity test.
