Just the IP is wall → change the domain name (resolved the shielded domain name to the domestic space, and then the 301 redirection to the new domain name to reduce the loss of traffic and weight). The domain name is shielded. It is best to immediately analyze this domain name and do not keep it on your server. Check the content of the website. If you do not find the content of violations, you can try to resolve the domain name to a large site in China. After a few days, it may be unblocked;

　　Set keyword shielding tools to directly block all keywords involved in the website. The cure method is to install a keyword interception system on your server and intercept the sensitive vocabulary, so that the site will not be blocked again. If there is no problem with the content, you can contact the local telecommunications and other ISPs to ask the other party to check, and sometimes they can help remove the website from the blacklist.

　　If the keyword interception system is not installed, the content of the website should be rectified. Check whether the relevant keywords have violated the regulations. If you can't check it yourself, the best way is to redo the website and ensure that the later domain names are not blocked.

　　The domain name is reset by the URL → replaced back to the domestic space, using the filing server to build a station. When using domestic servers, the shielding situation generally appears in foreign IP space manufacturers, and this situation rarely appears on domestic servers.

　　Distribution through domestic node CDN.

　　Note that the multi-IP server in Hong Kong is shielded by the connection to the domain name: After each visitor visits the shielded domain name once, it will not be able to access other sites on the same IP within 5-20 minutes. If the shielded domain name has been parsed to a certain IP, it will eventually cause the entire IP to be blocked. After the domain name is restored, please check the content of the website and delete illegal content to prevent being intercepted again.
