What should I do if the website is banned from accessing? Full analysis of reasons and handling methods

in the process of daily surfing the Internet or operating the website, the website is prohibited from accessing is a problem that many people have encountered. Whether it is browsing information, office collaboration or maintaining their own site, the sudden pop-up of the prohibited access prompt will interrupt the normal process and even bring business losses. This article will comprehensively disassemble the deep reasons for the website's prohibited access, analyze them one by one from the user side to the server side, and give a practical solution to help everyone solve this problem efficiently.

What are the common reasons why websites are blocked?

want to solve the problem of prohibited access to the website, first of all to find the root cause of the problem, the reasons in different scenarios vary greatly, can be roughly divided into three categories: client, server and compliance level.

1, client network or device problems

this is the most common shallow reason for the website to ban access, such as unstable network connection of the device, DNS resolution failure, or browser cache too much, plug-in conflicts, etc. Some users' devices may also be because of the installation of security software, mistakenly determine the target website as a risk site and intercept, resulting in normal access.

2, server-side failure

server is the basis for the operation of the website. Once the server is down, bandwidth is exhausted, configuration errors, etc., it will directly cause the website to be banned from accessing. For example, the server room is suddenly powered off, suffered from DDoS attacks, or the website program has code errors, database connection failure, will cause the site to fail to respond to requests normally.

3, compliance level limit interception

if there is illegal content on the website, such as pornography, violence, false propaganda and other content that violates the cyber security law, it will be shut down by the regulatory authorities, and then the prompt that the website is prohibited from accessing will appear. In addition, some websites may be forcibly suspended by the access provider because the ICP filing has not been completed, or the filing information has expired.

What should ordinary users do if they are prohibited from accessing the website?

as an ordinary browsing user, there is no need to panic when encountering the situation that the website is prohibited from accessing, and you can gradually check it in the order from easy to difficult, and quickly restore normal access.

1, check the local network and device

first check the network connection status of the device, try to switch the WiFi or mobile data network to confirm whether the website is prohibited due to network fluctuations. Then you can clean the browser cache and cookies, close unnecessary browser plug-ins, or try to access it with another browser to rule out browser-level blocking problems.

2, check the usability of the website

use the online website detection tool, enter the domain name of the target website, and check the server status and accessibility of the site. If the tool shows that the website can be accessed normally in other regions, indicating that it is a problem with the local network or operator, you can try to replace the DNS server, such as using a public DNS address, to solve the problem that the website is not accessible.

3. Confirm whether it is a compliance restriction

if the website access prompt clearly shows that it has been intercepted due to compliance reasons, then the user does not need to try to access, such websites often have security risks or illegal content, and continued access may bring equipment security risks, and even violate relevant regulations.

What should website managers do if they are prohibited from accessing the website?

for website managers, website access is directly related to business operations, the first time to locate the problem and solve, reduce losses.

1, quickly check the server status

first log in to the server background or through the service provider's monitoring panel to check the server's CPU, memory, bandwidth usage, and confirm whether the website is banned due to resource exhaustion. If it is attacked, turn on the firewall protection mode in time, contact the service provider to clean the traffic, and temporarily switch the backup server if necessary.

2, check the website program and configuration

check the error log of the website to locate whether there are code errors, database connection failure and other problems. At the same time, check the server's site configuration file to confirm whether the domain name resolution, port settings, etc. are normal to avoid the website being banned due to configuration errors. If it is a program problem, you can restore the latest backup version, restore site access first and then gradually troubleshoot bugs.

3, verify compliance with relevant qualifications

If you receive a notice of shutdown from the regulatory department or service provider, you must immediately verify whether the content of the website is in violation, rectify the non-compliant content in a timely manner, and submit the appeal materials as required. At the same time, check whether the qualifications such as ICP filing and SSL certificate are within the valid period to avoid the prohibition of access to the website due to qualification problems.

4, how to prevent the website from blocking access again?

solve the problem of prohibited access to the website, take preventive measures to avoid similar situations recurring and ensure the stable operation of the site.

1, do a good job in server maintenance

regularly check the performance of the server, clean up redundant files and logs in time, upgrade the system and program version, install security software, reduce the risk of server failure and attack. At the same time, configure the server monitoring alarm, once there is a resource abnormality or access fluctuation, you can receive the notification at the first time to avoid the development of serious problems that prohibit access to the website.

2, standardize website content and qualification management

establish a website content review mechanism, regularly check the content of the site, and ensure compliance with cyber security related regulations. Timely update ICP records, domain names, SSL certificates and other qualification information to avoid website bans due to expired or non-compliant qualifications. For user-generated content sites, it is necessary to strengthen content review to prevent illegal content release.

3, build a multi-dimensional backup solution

regularly backup the website program and database, using the dual scheme of local backup + cloud backup to ensure that the site can be quickly restored when the site is prohibited from accessing. At the same time, the backup server or CDN acceleration service can be configured to automatically switch when the main server fails to ensure the high availability of the site.

sum up, the reasons for the website to ban access cover the user side, the server side and the compliance level. Ordinary users can solve problems by troubleshooting network equipment and detecting site availability. Website managers need to start from server maintenance, program configuration, and compliance management. Do a good job of daily preventive measures, which can effectively reduce the probability of the website to ban access. Whether it is browsing or operating the site, it can ensure a smooth network experience.
