Facebook After being down for more than five hours and disrupting the digital lives of its billions of users, its family of apps, including Instagram, WhatsApp, Messenger and Oculus, began a comeback online late Monday.
A Facebook spokesperson confirmed that services are slowly coming back online, but cautioned that it will take some time for services to stabilize.
The social network-owned Facebook, Instagram, WhatsApp and other apps were shut down around 11:40 p.m. Eastern time on Monday.
It was very unusual for the world’s largest social media company to have so many apps going dark at the same time. More than 3.5 billion people use Facebook and its apps to communicate and do business with each other.
Facebook employees were also cut off from email, internal communication equipment, and physical access to construction sites due to outages.
The company did not disclose the reason for the outage. Security experts said the problem most likely arose due to misconfiguration of Facebook’s server computers, which were not allowing people to connect to sites like Instagram and WhatsApp.
