As most US residents are aware, the Citibank ATM/Automatic Teller Machine network failed last night. Citibank is still having problems today.
From Reuters:
"The Citibank ATM network and other systems experienced a temporary outage last evening." "While our systems were restored by early Wednesday morning, we have continued to experience difficulties this morning. We're working hard to resolve the issues as quickly as possible." 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.
