Chase's online banking service was lost in cyberspace for more than a day this week.
The banking website went down Monday night and was down all day Tuesday. A Chase spokesman said service was restored early Wednesday, but later Wednesday morning the site again carried a message saying service was unavailable.
North Texas customers reported Wednesday that the site was slow at times but was working again.
Chase customer Jeannette Breen said she uses The site to check her account balance and transfer money between accounts.
"It was unusual for it to be down," she said. I've never seen that happen before. I mean, it's faster than calling on the phone, because you have to enter in your account number, and your password and then they ask you for your name."
The banking site is popular with North Texans -- an Ad Council survey from May found that Chase.com was the top-visited website in North Texas.
Chase customer Brett Shevitz said it can be frustrating to not have online access to an account.
"Computers fail for whatever reason," he said. "You just need to roll with the punches."
"Luckily, I didn't incur any fees," Breen said.
Chase spokesman Thomas Kelly said Chase would work with any customers who had online bill payment deadlines they couldn't meet because of the outage.
The bank said it will refund fees incurred while the system was down. Customers can either go to a Chase Bank branch or call customer service.
