Just after 6 a.m. GMT, attempts to access Facebook brought up an error message telling users that "something went wrong" and the company was working on fixing the problem. The problem was resolved at 7.10 a.m. GMT.
Meanwhile, Instagram - a photo uploading site that is owned by Facebook - went to a blank page on a desktop computer and the mobile application failed to load new posts.
Chat app AIM and dating app Tinder were also hit by the outage, according to reports.
Instagram said on rival social media site Twitter at 6:51 a.m. GMT that it was aware of the outage and was working on a fix. "Thank you for your patience," it said in the message to its followers.
Facebook was not immediately available for comment.
During the blackout, disgruntled users took to Twitter - which was working as normal - to vent their frustration and poke fun at Facebook, which for many people has been a part of their everyday lives since its formal launch in 2006. Others used the microblogging site to poke fun at the situation.
The world's largest social network, led by CEO and founder Mark Zuckerberg, is due to report it fourth-quarter and full year earnings for 2014 on Wednesday.
It is not the first time that Facebook has experienced wide-spread interruptions.
Brief outages have occurred in recent years, but the most notable was in 2010. Facebook stated on its website that it was-at the time-the "worst outage we've had in over four years." It lasted for 2½ hours and was caused by an "unfortunate handling of an error condition."
In June last year, Facebook was briefly unavailable for 30 minutes, with users once again unable to log in. Reports from news wires at the time indicated that users from all over the world had been hit by the outage
