Until now, internet users have often misunderstood the 404 - Page Not Found error as a result of unstable internet connection. With the pervasive nature of the internet today, it is challenging to moderate all uploaded content. However, in every country, there are specialized teams responsible for moderation, blocking harmful websites that pose a threat to national interests and users.
The Most Frustrating Error Code 404 - Page Not Found
Distinguishing itself from the previous 404 - Page Not Found error code, the 451 error code comes into play to help users recognize blocked or malicious websites instead of receiving generic messages from their browsers.
The purpose of the 451 error code is to explicitly explain to users that the website they are trying to access has been banned by the government, marking a new standard for the internet. With the 451 - Unavailable For Legal Reasons error code, users can immediately recognize that the website can still be accessed when browsing with CocCoc or other browsers, but has been blocked in certain countries or regions. This provides clearer elucidation compared to the previous 404 error code, which merely indicated that the content or link being accessed did not exist.
The more advanced 451 error code assists users in understanding when a website is blocked
This error code was proposed by Google employee Tim Bray in 2012. The issue of malicious and subversive websites is a pressing concern in every country. As a result, each government has established barriers to block these malicious websites, preventing misleading information from reaching internet users. Therefore, the introduction of the 451 error code is deemed necessary to safeguard each country on the internet.
Recently, on December 18, 2015, the 451 - Unavailable For Legal Reasons error code was officially utilized on the HTTP protocol. The consensus of the IESG (Internet Engineering Steering Group) has paved the way for a new milestone in the online community.
The concept of using a distinct error code to indicate websites that are still accessible but blocked was inspired by Tim Bray's blog post, sparked by Terence Eden's encounter with a '403 Forbidden' error while attempting to access The Pirate Bay, a website banned in the UK.
