Earlier this day, one of the websites on my server cannot be reached. After checking, I found the cause was the domain had not been authenticated.
According to Chinese Internet network domain name management method, .xin /.cn/.com/.net/.top/.xyz/.club/.vip/.shop/.wang/.ren/.site/.我爱你/.集团/.biz/.red/.kim/.pro/.info/.mobi/.ltd/.group/.link/.ink/.在线/.中文网/.网址/.work/.online/ .tech/.fun/.store/. must have real name authentication。Otherwise, it will be in the status of Serverhold.
