Users worldwide are reporting that they are unable to access Facebook, Instagram, and WhatsApp, instead seeing errors that the sites can't be reached.
When attempting to open any of the three sites, they are given DNS PROBE FINISHED NXDOMAIN errors and advised to check if there is a typo in the domain entered in the address bar.
"This site can't be reached. Check if there is a typo in facebook.com. If spelling is correct, try running Windows Network Diagnostics," the error message says.
A Facebook spokesperson was not immediately available for comment when contacted by BleepingComputer earlier today.
While the company has not yet provided an explanation for this outage, in BleepingComputer's tests, the Facebook, Instagram, and WhatsApp DNS servers are not responding, which would suggest that this is a DNS configuration or server issue.
