On 4th of October 2021, you can no longer connect to the main Social Networks. Facebook is facing a global outage affecting all its services. He is not the only one. Messenger, Instagram and wahtsapp are also affected. In computer terminology, servers are “down”. All devices are affected: from personal or desktop computers to mobile devices such as smartphones or tablets. The most common message displayed is this: DNS_PROBE_FINISHED_NXDOMAIN. This message does not therefore come from a problem on your device but from problems connecting to social network sites; so this is also a DNS problem.
