The Next Web says it has contacted Facebook Inc (NASDAQ:FB) for clarification on the outage, although it says “some form of DNS error would seem likely” because not all users of the social media site are affected. Thus far reports from various Facebook users on Twitter seem to indicate that the site has been down for more than an hour, and DownRightNow’s report shows that we could be going on .

A similar outage happened last October, and Facebook Inc (NASDAQ:FB) said at that time it was changing to DNS to test traffic optimization. Also on Thursday a glitch on Facebook’s site took down many sites which use its login credentials.

That outage lasted just a short time but affected many major news and tech sites, like Mashable, The Washington Post and CNN. In that outage, users who tried to go to those sites were redirected to an error page on Facebook. Users had to log out of Facebook in order to avoid the bug.

These widespread outages show just how far-reaching Facebook Inc (NASDAQ:FB) has become. It is now part of the daily life of people all over the world, so when it goes down or causes other sites to go down, the effect is dramatic.
