The Facebook application family is down for users in certain parts of the world.
Facebook, Instagram, WhatsApp and Facebook Messenger did not load early Sunday morning.
Downdetector.com, a site that monitors site failures, shows that Facebook has been down since 6:30 in much of the world, with thousands of reported outages concentrated in the northeastern US, Europe, and in the Phillippines.
The cause of the failure and the downtime of the platforms were not yet clear.
Associated Press sent an email to Facebook to ask him to comment on the crash.
#FacebookDown, #instagramdown, and #whatsappdown were all trends on Twitter around the world.
Facebook, which has seen many scandals regarding privacy, content moderation and election integrity in recent years, acquired Instagram in 2012 and WhatsApp in 2014.
According to the social media network website, more than 1.52 billion daily users are active on Facebook.
