Users were reporting performance and availability issues with Facebook Monday. Some complained on Twitter of slowness and pages that didn't load. Others said that third-party desktop apps that connect to Facebook (such as Digsby) lost their access to the service.
The outage did not appear to be widespread. A spokesperson for Facebook said in an e-mail to CNET:
As a result of a network device failure, a very small percentage of users lost access to Facebook for a short period of time earlier today. The site has now been restored and we apologize for any inconvenience this may have caused.
