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

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

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.
"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.
