According to reports, BofAâs main website crashed on the morning at 07:00 ET before being restored just after 17:00 ET that same day.
Tara Burke, a spokeswoman for the financial services provider, said that the issue only affected a small number of the bankâs 29 million online customers and was due to an overnight routine change to systems.
The majority of customers were able to access their bank accounts while a smaller fraction could not log in to their accounts or experienced a slow service as a result of the change, she explained.
Ms Burke added that this was not the result of a hack and stated: âThis has nothing to do with malware, WikiLeaks or any type of attack.â
The comments follow speculation that BofA could be the next target of a release of information from the whistle blowing website.
In an interview with Forbes magazine, WikiLeak founder Juliun Assange said that a âmajor financial institutionâ will be involved in the next leak by the site.
