Facebook, Instagram and WhatsApp returned to work on Sunday morning after being useless for a few hours.
Downdetector.com, a site that monitors site disruptions, showed that Facebook was inactive from 6:30 a.m. in much of the world, with thousands of interruptions reported in the northeastern United States, Europe and the Philippines.
By 9:00 the services had mostly resumed.
It was not immediately clear what caused the interruption.
An email requesting comments on the cut was sent to Facebook.
#FacebookDown, #instagramdown and #whatsappdown are trends on Twitter worldwide.
Facebook acquired Instagram in 2012 and WhatsApp in 2014.
There are more than 1,520 million daily active users of Facebook, according to the social network.
Previously, on March 14, there was a partial fall of Facebook, which also affected Instagram and WhatsApp, and lasted 22 hours, one of the longest in the history of the US company.
On that occasion, the firm that directs Zuckerberg explained that the incident was caused by a "change in server configuration", which had repercussions in countries around the world.
