The outage doesn't appear to be affecting all users, and the cause for issues aren't immediately clear.
The world was thrown into darkness after Facebook went down on Saturday night (Indian Standard Time) with users unable to access the site. Here is a compilation of some of the best tweets to come out of the trending #facebookdown on Twitter this morning.
Instagram users are joining those Facebook subscribers who can not log into their accounts, or are having other problems. In April of 2012, Instagram was purchased by Facebook for $1 billion.
According to DownDetector, Facebook had some issues since 9:12 AM EDT. The error had left users across the globe unable to share links or post articles on their pages.
The sites were not loading for many users.
"It's back! I just woke up, have coffee, and only was "Facebook-less" for about 10 minutes", wrote one user. Let us know down in the comments.
The app appeared to be working again at about 3.40pm United Kingdom time, and a temporary outage on Facebook seemed to have been rectified at about the same time.
