Re: ATM failure - No the other kind of ATM

["Steven M. Bellovin" <smb () research att com>]

According to today's Wall Street Journal, Citibank is explaining
the outage as "software", and declining to release further details.
But the article also noted that

        many of the computer systems on which banking networks
        are based are aging -- and trouble-shooters who can fix
        problems quickly are becoming rarer. Indeed, most banks
        and Wall Street firms run on a mishmash of systems slapped
        together after years of computer upgrades and bank mergers.
        hey are made all the more confusing by the profusion of
        computer languages that run the Internet. Most of them are
        incompatible with their mainframe predecessors.
