The global economy lost billions of dollars as Facebook, WhatsApp, and Instagram went down at about 4.42pm on Monday.
According to NetBlocks, which tracks internet outages and their impact, the outage had already cost the global economy about $160m per hour.
Facebook stock had gone down by about 5.5 per cent. The Chief Executive Officer of Facebook, Mark Zuckerberg, also lost nearly $7bn since the outage began.
Facebook and its affiliates have 2.9 billion monthly active users. The shutdown is reminiscent of 2019, when Facebook shut down in its biggest outage till date (a 24-hour shut down).
For hours when navigating to Facebook, Instagram, and WhatsApp websites, a server error appeared, which indicated there was an issue with Facebook’s servers.
According to TechCrunch, users were also unable to send messages or load new content on the mobile apps for these platforms. Even Oculus, Facebook’s virtual reality platform, and Workplace, its business communication tool, were down.
It seems as though the outage was caused by a domain name server failing, the naming structure that forms the web’s infrastructure.
