Citibank, used by 200 million Americans, was hit by a nationwide outage.
The bank’s website showed an error message: ‘We’ve encountered an issue and are working to fix the issue.’
No other details have been provided except for customers to return to the website 10 to 15 minutes later.
The issues were fixed around 2pm ET. A Citibank spokesperson told DailyMail.com: ‘A limited subset of credit card users were briefly affected by a technology issue that has since been resolved.’
Downdetector, a site that monitors online outages, showed issues hit around 10am ET, with credit cards and mobile banking cited as not working.
An outage map showed New York City, Chicago, Dallas, Los Angeles and other major cities across the US are experiencing problems.
