• WatchMouse web site monitoring service - Social networking sites slow and inaccessible
  In recent research, WatchMouse found that many of the world's largest online social networks have poor site performance, leaving users waiting for sites to load or encountering errors. Of the 104 sites monitored, the immensely popular Facebook (facebook.com) site was the worst performer; recording a slow load time and more errors than any other monitored site.
