The internet world seemed to be coming to an end for several hours earlier today when the Facebook website went down. The majority of the world could not access Facebook at certain points of the day. Most users were getting errors saying “Service Unavailable – DNS Failure”. We have good news now though. Facebook is back up and running.

A representative from Facebook said the following in a recent email reported by CNN:

“Today we experienced technical difficulties causing the site to be unavailable for a number of users. The issue has been resolved and everyone should now have access to Facebook. We apologize for any inconvenience.”

Facebook first went down around 11:30 AM EST in some parts of the world, but was fully restored by 5:30 PM EST.

If you were to take a look at Twitter while Facebook was unavailable, you would have seen how much anxiety was being experienced by people who needed to get their hourly fix of the popular social networking website.

There were literally hundreds of tweets posted per second about the DNS failure that Facebook was experiencing.

What caused Facebook to go down? There is no official word as of yet.

All is back to normal now, so you can relax, chat with your friends, and make your routine status updates.
