The main site for Chase bank was temporarily inaccessible for some today, one day after Bank of America's online banking site had intermittent outages.
"*ALERT* Chase Online is working, though some customers may not get in on the first try. We appreciate your patience as we work through this," the Chase Twitter account tweeted this afternoon.
This morning the message was: "Chase.com is experiencing intermittent issues. We're working to restore full connectivity and apologize for any inconvenience." CNET was unable to access the consumer banking site, Chase.com, but able to get to JPMorgan.com today.
After Twitter users continued throughout the day to complain about the outage and ask if the company had been hacked, the account responded this afternoon: "We're just experiencing intermittent problems with the site. It's working for some customers now. Update to come."
A J.P. Morgan Chase spokesman provided CNET with this statement: "The site is up, though some customers are having trouble getting on. We're working on it and apologize for the frustration."
Meanwhile, the Financial Services Information Sharing and Analysis Center raised the threat level for attacks from "elevated" to "high" citing "recent credible intelligence regarding the potential" for distributed denial-of-service attacks.
Yesterday, Bank of America was scrambling to rectify whatever was causing "occasional slowness" for many customers, a problem that was still happening for some today, according to CNN.
Asked whether the Web site was the victim of a denial-of-service attack, Bank of America spokesman Mark Pipitone told Reuters yesterday that: "I can tell you that we continuously take proactive measures to secure our systems."
Also yesterday, a warning from "cyber fighters of Izz ad-din Al qassam" was posted on Pastebin threatening to attack Bank of America and the New York Stock Exchange over the release of the controversial video mocking Prophet Mohammad. The film has sparked a furor and led to demonstrations and the death of the U.S. ambassador in Libya and three others.
Updated 3:27 p.m. PT with Chase tweet saying the site is "working" and financial industry group warning about increased threat of attacks.
