The quickest way to destroy a financial system, in this case our electronic system, is to destroy any trust or faith that the depositors and users have in the system. This electronic warfare on our financial institutions could have been perpetrated by foreign hackers, possibly backed by a doreign government, or, it could have come from within our own government. Trust, once lost, is seldom regained.
not to worry, your money is backed by the full faith and credit of our feral gubmint.
