Story updated to reflect the return of some service. NEW YORK ( TheStreet) -- Bank of America ( BAC) online customers that were being told that, "online banking is temporarily unavailable," may now find their sites are back and functioning. A spokeswoman for BofA said that some states' online banking was back in service, but she would not specify which states were still experiencing problems. The Bank of America website has been slow since Monday due to routine upgrades over the weekend. A Bank of America representative said that the bank is trying to get services restored as soon as possible but did not offer a timeframe. "We are experiencing a disruption in our service. There has been no impact to customer information or security compromises," said a BofA spokeswoman. Several customers have also complained that the web site has been down during the day. The outage is the second this year. In mid-January Bank of America also experienced similar problems. --Written by Maria Woehr in New York.
