Bank of America's website appears to be having issues today, with slow load times and occasional messages saying the site can't be accessed.
"The website is not down, it’s available, although some customers may experience occasional slowness," spokesman Mark Pipitone said in an email. "We are working to ensure full availability. Customers may use other channels such as ATMs and banking centers to conduct their business, if necessary."
He said the bank is looking into the cause of the difficulties.
Fox Business reported that a source told them the site was down because of a cyber attack from a group claiming to be affiliated with an Islamic terrorist organization. The group wrote on a site called Pastebin earlier today that they would launch an attack on Bank of America and the New York Stock Exchange starting at 2 p.m. They said the attack would continue until the controversial video that mocks the Prophet Muhammad and Islam is taken down, according to the message.
The bank did not confirm or deny the rumors, but Pipitone wrote: "We continuously take proactive measures to secure our systems."
Last October, the bank's website was down or slow for the better part of a week. While Bank of America did not disclose the reason for the issues, a spokeswoman said it was not because of hacking or malicious software.

No idea if it's really a DDOS attack by the "Ezzadeen al-Qassam Brigades" but the Bank of America website is definitely down. #BofA
