NEW YORK (Dow Jones)--Bank of America Corp.'s (BAC) website has been  slow since mid-afternoon Monday, though patient customers "can still  bank," according to a spokeswoman, who said the banking giant isn't a  victim of a cyber attack and none of its customers' personal or account  data have been compromised. 
   Spokeswoman Tara Burke said the slowness was a result of "routine"  upgrades made over the weekend, and the slowness isn't affecting any  particular geographic area. The company is working to restore normal  service "as quickly as possible," she said, but she couldn't provide any  timeline for a resolution. 
   The problem mirrors one reported in mid-January, which Burke at the  time said was affecting a "very small population" of its customers. On  Tuesday, Burke wouldn't quantify what percentage of the 29 million of  its customers who bank online are affected by the current slowdown. 
   Bank of America shares were off 18 cents, or 1.3%, at $14.11 in recent Tuesday trading.
