The ATM's did not work in the immediate NY area. The ATM's and credit card processors in other parts of the country still worked fine. Even so, after this event, banks and the big credit card companies have invested millions of dollars in improving their infrastructure with multiple redundancy points and automatic load shifting of processing so that one large area interruption does not effect other areas.
If the banks are using redundant data back haul that feeds thru the same C.O. or even the same manhole in the street, it may still be killed out by damage to those structures. You would be surprised how many times I have seen major companies tout their redundant backup plans, only to have the fiber for each redundancy share a telco conduit underground.
This just got me to thinking of a past incident or two during my time with the LEC telephone company. I shall start a new thread.
My question to all is: Do you live in a single strand community?
