[]

Since there is very little "unique" network equipment in the world now, just about everyone buys equipment from the same vendors. So the question is, Can we learn anything from Citibank's experience. Is there anything about their continuing problems which may be used to improve general network reliability?

I tried to find out some information from Citibank's web site about the issue, but I didn't see anything. []

[] In my experience, banking ATM networks tend to use pretty odd equipment. Most ATM networks tend to be leased lines or use FRADs that speak the teller machine lingo. Some banks use boxes that encapsulate the protocol in TCP, so I guess that a failure there could be a big problem. --Chris
