Facebook is down with its key features unavailable for some users globally for the last 8 hours. The magnitude of the outage is bigger and more people are affected this time than ever before. Other than Facebook, the company's messaging app WhatsApp and photo-sharing site Instagram were also affected.
"Facebook is down for required maintenance right now, but you should be able to get back on within a few minutes. In the meantime, read more about why you're seeing this message. Thanks for your patience as we improve the site," a message on the website read.
The outage affected users in the US, Europe, South America, Australia and Asia, according to a map by Down Detector.
On Twitter, hashtags #FacebookDown and #InstagramDown have been used more than 150,000 times so far.
Instagram, it seems, is back up after suffering a partial outage for over several hour.
