JPMorgan Chase Thursday afternoon that the attacks

he main website for JPMorgan Chase (JPM) was not reachable today, one day after Bank of This country's (BAC) internet financial website had sporadic failures.

"*ALERT* Chase On the internet is operating, though some clients may not get in on the first try. We appreciate your perseverance as we work through this," the Pursuit Tweets account tweeted this mid-day.

This day the information was: "Chase.com is suffering from sporadic issues. We're wanting to recover full connection & say sorry for any difficulty," the company said on Tweets today. CNET was incapable to access the individual financial website, Chase.com.

After Twitter users continued throughout the day to complain about the outage and asking 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 JPMorgan 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."

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 website 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.
