Some time ago, there was a worldwide failure of all popular social networks. Below is the most important thing: - Facebook employees cannot get into their offices to solve problems with the company's services due to the failure of the security system of the complex in which the network's headquarters is located. - Mark Zuckerberg lost $ 6.6 billion due to Facebook, WhatsApp and Instagram crashes. The billionaire dropped to 6th place on the Forbes list. - While Facebook is in the blackout, the personal data of 1.5 billion Facebook users were sold on the black market, which was the largest hack of the social network in its history. The data includes logins, contact phone number, address, favorite locations, data of linked accounts, including taxis and banking companies. - According to the specialists of the Facebook company, which owns WhatsApp, it will take about five hours to completely fix the problem. - "The fall of the network is not related to hacking," - said the security service Facebook.
