Problems disable ATMs at Wells Fargo for 24 hours

Service problems disabled ATMs and online accounts at Wells Fargo & Co. for at least 24 hours starting Sunday afternoon, leaving some customers of the nation's fifth largest bank unable to get cash or use debit cards to pay for goods.

San Francisco-based Wells Fargo would not say how many customers or machines were affected but acknowledged that services were down throughout the company — from personal banking and Wells Fargo corporate Web sites and ATMs to the processing of mortgage and student loans.
