In news that will surely be greeted warmly at Twitter HQ, Facebook, Instagram, WhatsApp, and Messenger have all gone down in a huge global outage. Tens of thousands of users have reported issues accessing the four Facebook-owned platforms, according to the DownDetector website. Reports of problems began flooding in at around 17.30 CET. Since then, many users have been receiving error messages when they try to access the services. The issues appear to have been caused by a Domain Name Server (DNS) failure.
