in the process of daily use of the network, many people will encounter the situation that the website is suddenly inaccessible. At this time, it is necessary to distinguish whether it is a network failure or a problem with the website itself. Whether the website is blocked is one of the directions that needs to be investigated. Especially for website managers, timely confirmation of whether the website is blocked can avoid user churn and ensure the normal operation of the business. This article will share a super practical online detection tutorial for you, covering a variety of verification methods and judgment skills, to help you quickly and accurately confirm whether the website is blocked and solve the confusion of inaccessible websites.

, is the website wall based online detection method?

online detection tool is the most convenient way to confirm whether the website is wall, no complicated operation, novice can quickly get started.

1, use professional online testing platform

there are many online platforms on the market that specialize in detecting whether a website is blocked. These platforms usually conduct access tests on the target website through a multi-node server, which can quickly give feedback on the results. For example, Webmaster Tools, Love Station and other platforms provide relevant detection functions. Just enter the website domain name and wait a few seconds to see the test report. The report will clearly mark the access status of the website in different regions of the country and whether there are signs of being blocked. Such platforms have more comprehensive data and will also come with other SEO-related information of the website, which is suitable for long-term use by website managers.

2, with the help of overseas node detection tools

In addition to the domestic detection platform, you can also use the detection tools of overseas nodes to confirm whether the website is blocked. Such tools access the target website through overseas servers. If the overseas can be accessed normally but the domestic cannot be accessed, the probability of the website being blocked is very high. For example, some overseas website monitoring tools support entering the domain name to view the access status of different parts of the world. Compared with domestic and overseas access data, you can clearly determine whether the website is blocked. However, some of these tools need to register an account, and some functions may need to be paid, but the accuracy of the detection results is high.

2, the site is the wall of manual verification skills?

if you have doubts about the test results of online tools, or want to more accurately confirm whether the website is blocked, you can judge by manual verification, which is more suitable for users with a certain network foundation.

1 Modify the local DNS server test

DNS abnormal resolution may cause the website to be inaccessible, easy to be confused with the website by the wall, so it can be checked by modifying the local DNS server. Modify the computer's DNS server to public DNS, such as 114.114.114.114 or 8.8.8.8, and try to access the target website again after the modification is completed. If it can be accessed normally, it means that it is a DNS resolution problem, not whether the website is blocked; if it is still inaccessible, it is necessary to further check whether the website is blocked. The operation steps of modifying DNS are relatively simple and can be completed in the network settings of the computer. Before the operation, the original DNS address can be recorded to facilitate subsequent recovery.

2, use the Ping command and the Tracert command

through the command prompt tool of the computer, using the Ping command and the Tracert command can also help determine whether the website is blocked. The Ping command can test the connectivity of the local to the target website server. If the Ping command returns a timeout or a high packet loss rate, it indicates that there is a problem with network connectivity; and the Tracert command can track the transmission path of the data packet and see which node the data packet is interrupted at. If the data packet is interrupted at the domestic node and the overseas node can be transmitted normally, then the website is very likely to be blocked. However, the results of these two commands need to be analyzed in combination with network knowledge, which is suitable for user operations with a certain foundation.

Third, whether the website is the result of the wall judgment points?

whether using online tools or manual verification, it is necessary to master the correct results to judge the key points in order to accurately confirm whether the website is blocked and avoid misjudgment.

1, distinguish between network failure and website wall

many times the website cannot be accessed because of local network failure, server downtime or the maintenance of the website itself, not the website being walled. Therefore, when judging, you must first rule out these factors. You can try to visit other websites. If other websites can be accessed normally, it means that there is no problem with the local network. Then try to access the target website through multiple devices. If all devices cannot be accessed, you need to further confirm whether the website is walled. In addition, you can also check the official announcement or social media account of the website to see if there is a maintenance notice to avoid misjudging whether the website is walled.

2, combined with multi-dimensional data comprehensive judgment

confirm whether the website is wall can not only rely on a single test result, it needs to be combined with multi-dimensional data comprehensive judgment. For example, using the online detection platform, overseas node tools and manual command detection at the same time, if the results of the three methods all point to the website being wall, then the accuracy is very high. You can also ask friends in different regions to help test the visit. If different regions in China cannot be accessed, but overseas can be accessed normally, you can basically determine whether the website is wall. Comprehensive multi-faceted data can effectively reduce the probability of misjudgment and make the judgment results more reliable.

4, whether the website is the wall of the investigation error need to pay attention to?

in the process of confirming whether the website is blocked, many people will fall into some misunderstandings, resulting in inaccurate judgment results, which need to be understood and avoided in advance.

1, draw conclusions based on only one test

some users directly determine whether the website is blocked after using an online tool to detect, this practice is not rigorous. Because online detection tools may have wrong results due to temporary server failures or network fluctuations, especially free detection tools, data updates may not be timely. Therefore, it is necessary to use different detection tools for testing multiple times, or to detect again at intervals to ensure the consistency of the results, in order to accurately determine whether the website is blocked.

2, ignore the website's own problems

many people in the website can not be accessed, the first time to doubt whether the website is wall, but ignore the website's own problems, such as server expiration, program error, domain name resolution abnormality, etc. These problems will also lead to the website can not be accessed, and the website is similar to the performance of the wall. Therefore, in the investigation, first check the website's server status, domain name resolution records and whether the website program is normal, eliminate these own problems, and then confirm whether the website is wall, to avoid useless work.

sum up, to confirm whether the website is wall needs to combine online detection tools and manual verification methods, and at the same time master the correct results to judge the key points and avoid the misunderstanding of investigation. Whether it is website managers or ordinary users, they can quickly and accurately confirm whether the website is wall through this method, and take corresponding solutions in time to ensure the smooth use of the network.
