Amazon.com's Web site is having more trouble.
The extent of the problem isn't yet known but some attempts to reach the e-commerce site Monday have resulted in "service unavailable" errors.
The site was down for about two hours on Friday. Amazon.com Inc. blamed that outage on system issues.
Amazon officials did not immediately return a phone call Monday.
Keynote Systems Inc., a California-based company that measures Web site performance, would only say it was monitoring the "fluid situation" at Amazon.
