I was having trouble accessing Facebook: my browser was displaying a blank page when I went to the site. This happened on two browsers I tried, Internet Explorer and Google Chrome. Wanting to determine the status of the Facebook website, I typed in "Is Facebook Down?" in a search engine and found DownRightNow, specifically the Facebook status page. Sure enough, it showed that there is a "likely service disruption". It's a handy site I have bookmarked for future use.
