Facebook said some users were briefly unable to access the site because of a technical glitch.
The social networking site with more than one billion users worldwide said on Monday it made a change to its domain name system set-up. The change resulted in some users temporarily not being able to reach the site.
The problem was detected and the site is now fully back.
A DNS acts like a phone book for the Internet, translating a domain name like facebook.com into a number that points to a specific host computer.
Facebook did not say how many users were affected or for how long. Some technology blogs say the problems lasted about 20 minutes.
