NEW YORK (CNNMoney) -- Some Bank of America customers trying to access their online and mobile accounts were unable to get through on Friday -- an issue the bank says it is aware of and working to resolve.
"We are experiencing some sporadic issues for a small population of customers," spokeswoman Tara Burke said Friday afternoon. "The majority of our customers can bank online."
The outage was widespread enough to prompt a torrent of complaints on Twitter. It also kept Bank of America's official Twitter account, @BofA_Help, busy tweeting out a steady stream of replies.
"We are aware of the problem and are working to get things sorted as swiftly as possible," the company tweeted.
An IT glitch triggered the problem.
"This was the result of a routine system change made last night," Burke said. "This is not a form of malware, or any attack or anything related to WikiLeaks."
But Friday's slowness and intermittent inaccessibility was simply a technical malfunction, Bank of America says. Chase.com suffered a similar outage in September -- but that one lasted three days and affected more than 16 million customers.
