While the exact mechanism of BofA's exposure is important it is
nowhere near as important as the fact that they were, and presumably
are still, exposed.  My money's on Frame Relay congestion.

Some department at BofA, short on engineers and long on budget-oriented
management, likely made a decision that saving a lot of money was
worth a bit of exposure.  I know that decision has been made at
other banks.
