Better wild guess. This weekend Citibank was merging with EAB, and was trying to merge the two ATM networks...I assume this problem is dealing with trying to merge 2 disparate networks.

Folk, The story I read referred to a software glitch resulting from unusually high volume over the Labor Day weekend. Most ATMs use OS2 (stand around one until the maintenance person re-boots it). My WAG (wild a** guess) is a fixed length field somewhere, say X,XXX,XXX, and the network had 10,000,000 whatevers over the Labor Day holiday that was then repeated when it came back up due to the pent-up demand from the system being off line. When was the last time you took a look at any data that increments in fixed length fields? Your mileage may vary. -Al -----Original Message----- From: Sean Donelan [mailto:sean () donelan com] Sent: Wednesday, September 05, 2001 1:11 PM To: nanog () merit edu Subject: ATM failure - No the other kind of ATM 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.
