Or, IIRC, the ATM system is similar to CC transactions. A best effort is made to authorize against your account (Credit Card or Banking) but if it fails and the transaction is within a normal range (your daily card limit) the CC/ATM completes the transaction. I'd be willing to bet the failure rate Saturday was high enough to cause concern that bank customers (knowingly or innocently) could bypass the normal limits and overdraw or otherwise negatively effect their accounts. So BoA decided to shut down the system until the failure rate returned to 'normal.' Not a bad thing, IMHO. Best regards, ______________________________ Al Rowland

"About 13,000 Bank of America cash machines had to be shut down. The bank's ATMs sent encrypted information through the Internet, and when the data slowed to a crawl, it stymied transactions, according to a source, who said customer financial information was never in danger of being stolen."
