The bank said it was experiencing a “technical issue” with a third-party vendor, impacting some account services like deposits and payment processing.

FIS Global, the Capital One service provider involved, said it has "restored access" and processing should be done Friday.

Capital One’s outage comes just a day after Citibank admitted that its own tech issues were keeping cusotmers from accessing their accounts from their mobile devices. Citibank also revealed that incorrect fraud alerts had been placed on customers’ cards, and that the bank was working to clear up the problem.
