Yesterday the domain name to facebook?

Website DNS resolution problems, I come from China, the website can not be accessed in China. All parts of China.

More seriously, yesterday domain directly jump to Facebook.com

What is the problem?

If you are the site owner and concerned that your password may have been compromised you should login to your account and change your password immediately. If you are visiting a site behind Cloudflare that is having issues you should contact the site operator directly.

The password is safe.
But my domain name is not accessible in China?

Looks like this is a duplicate thread. Going to close it and will attempt to respond on the other one.
