Facebook, WhatsApp, and Instagram have been down for six hours, considered extremely long for the platforms.
Some Twitter users who work in "Facebook-centric" jobs, expressed their panic and distress at being unable to use the platform.
Several of Facebook's products are suffering partial outages, affecting users globally. That's a reference to a distributed denial-of-service brute-force attack, in which networks are overloaded with bogus traffic created to disrupt service.
Facebook shared on Twitter Wednesday just before 1 p.m. that they are experiencing a wide-spread issue impacting users' ability to post and share.
Others are seeing a red box which states that Facebook is down for "required maintenance" but will be back up "within a few minutes" or "a few hours". As of 4:45 EDT service was restored to some but other users were still reporting problems.
According to downdetector.com, Facebook is said to be down from around 9.30 pm in India.
The social media giant, which owns Instagram, said it was aware of issues people were having with Facebook's suite of apps. Many people report a similar problem in which they can see their timelines but cannot make posts.
Third-party outage tracker Down Detector said the worst hotspots were in California and NY in the USA, and in the UK.
However, when switching over to desktop, the issues became even more apparent.
