The sudden Facebook outage on Monday left hundreds of millions of people around the world without their go-to source for news, current events, recipes and local gossip. The outage crippled not only Facebook and its app, but also Instagram and WhatsApp.
The outage happened around 1 p.m. ET in the United States, and it wasn’t restored until five hours later. Facebook engineers at 10 p.m. ET—nine hours after the outage and four hours after restoration—explained the reason behind it.
Facebook said it was “sorry for the inconvenience” on its multiple platforms for those who use them for both personal and business reasons.
