Facebook Chief Technology Officer Mike Schroepfer apologized to the company’s advertisers and businesses who depend on Facebook for the social network’s massive global outage on Monday.
Facebook services coming back online now – may take some time to get to 100%. To every small and large business, family, and individual who depends on us, I'm sorry.

Late Monday morning, Facebook, Instagram, WhatsApp, and Messenger all went down, and service wasn’t restored for about 6 hours.
Monday’s outage reportedly cost the company $60 million in revenue. Facebook co-founder Mark Zuckerberg saw his personal net worth decrease by about $7 billion.
