there are other payment processors out there for mastercard and visa,
im sure in canada I dont bother clearing the charges I put through with
a single master server in the US, they're probably also distributed
for various reasons (fibre cuts speed of transaction, etc). When I hit
the bigger grocery stores, the approval is almost instantaneous. Not
sure what they're using for backhaul to where, but it aint DSL or a phone
line.
Taking out that kinda distributed architecture would require attacking the
protocol with a self propagating attack (~Stuxnet), not the individual
sites that do the processing.
Im sure Mastercard has some skills on how to run an internal 'cloud'.
