SEATTLE (AP) -- Online retailer Amazon.com's Web site went down for more than two hours in the middle of the day Friday.
Around 10 a.m. PDT, the Web site shut down, giving an error code to anyone visiting it, according to Keynote Systems Inc., a California-based company that measures Internet activity.
Shawn White, Keynote's director of external operations, says an error in the configuration of the Web site might have caused the shut down.
White says another reason might have been be server overload, but he says Amazon has a history of being able to handle large loads of visitors.
Calls to Amazon.com were not immediately returned.
White says the Web site was back up to 60 percent capability around noon.
