Chase online banking system suffers some outages

JPMorgan Chase's online banking system suffered some outages Thursday evening.

Customers could log into the bank's website or app, but they are unable to transfer money or pay bills online. Most disturbingly, Chase shows "N/A," where the account balances should be.

A customer service representative said debit cards should still work for purchase transactions, but she noted that the bank's website and app were out of service for the service team, as well. The representative told CNBC to call back "in a few hours."

Chase later said: "We are currently working to restore access to our website, mobile app and automated telephone service."

Chase customers took to Twitter to vent their frustration.
