Facebook suffered its worst-ever outage on Wednesday 13th March. The downtime, which also hit related products Instagram, Messenger and WhatsApp, lasted for at least 14 hours, CNN reported.
The blackout hit millions of users across the globe and caused Facebook stock to tumble 2 percent in after-hours trading.
Every minute that Facebook is offline costs an enormous amount of money. By extrapolating from the company’s 2018 revenue figures, we can estimate that yesterday’s blackout could cost Facebook up to $90 million in lost revenue.
We’re aware that some people are currently having trouble accessing the Facebook family of apps. We’re working to resolve the issue as soon as possible.
