HTTP Error 410 - How to quickly remove content from Google & Co

The HTTP Status code plays an important role in ensuring secure and reliable communication over the Internet, maintaining the integrity of information, and identifying the origin of problems. The Status code 410 Gone is one of the definitive and permanent error messages in this context, although it appears relatively rarely compared to other messages such as the HTTP Error 404 Not Found or the 502 Bad Gateway. Despite its rarity, due to its significance and impact, it represents an important 400 Status code that an Internet user should be familiar with in order to interpret it appropriately.

What does a 400 Status code indicate?

The current standards on the Internet define public documents known as Request for Comments (RFC), inviting all interested parties to comment. They also describe the process of communication via the Hypertext Transfer Protocol (HTTP) used for websites and the possible responses to a request, which may include additional information or indicate successful processing or an error in retrieving data. These are:

• Status code 100 - 199 includes supplementary information such as an ongoing process
• Status code 200 - 299 indicates successful processing of the request
• Status code 300 - 399 signifies a redirection to another resource or new address
• Status code 400 - 499 indicates a likely error caused by the client
• Status code 500 - 599 denotes a problem with processing on the server
• Status code 900 - 999 are unofficial and used by proprietary software

Specifically, a 400 Status code means that the web hosting on a dedicated or virtual server is functioning as intended, but the client is sending incomplete, erroneous, or incorrectly addressed requests. The most common example of this is the HTTP Error 404 Not Found, indicating the absence of a specific address. Similarly in statement is also the Status code 410 Gone - however, the consequences differ from each other.

What is the difference between Status code 404 and Status code 410?

Although both error messages describe the same issue - a webpage does not exist at a specific address, the status code 410 Gone and the 404 error indicate a different origin. The term "Gone" in the description can be translated from English as "Verschwunden" or "Vergangen", while an HTTP Error 404 stands for a non-specific "Not found", without providing a hint to the reason. In practice, this means that with a status code 410, certain common triggers can be ruled out. It specifically states that:

• An address or resource existed in the past
• It is no longer present at the current time
• No communication issues between client and server are occurring
• It is a permanent change that will not be reversed

In practice, many administrators in web hosting avoid using the status code 410 Gone because they want to avoid the additional effort in configuration or may not be able to assess whether the relevant address is permanently no longer in use. In this case, the browser instead displays the standard cause HTTP Error 404.

However, the crucial difference is that a browser stores Gone as a permanent 400 status code in its cache. Upon a subsequent visit, it does not establish a connection to the web hosting, but locally reports the webpage as unavailable. A similar effect is seen with the status code 410 in the databases of search engines. They interpret it as a clear indication that a specific resource is permanently unavailable and therefore remove pages from their results if they display a status code 410 Gone. For this reason, administrators and SEO experts also deliberately use it to have certain content deindexed. This originally important function has, however, lost significance since the Google Search Console has also allowed for temporary or permanent removal of web pages from the company's index since 2011.

How can a status code 410 Gone be resolved?

However, in some cases, the reverse situation also occurs: An administrator mistakenly marks a subpage or an entire website with the status code 410 Gone for their web server, even though it is only temporarily unreachable. This can be problematic because the browser retains this information and uses it for an extended period. For the visitor, the address will still appear offline even when it is back online. This issue often arises with virtual or dedicated servers that are not managed by a professional administrator and where configuration errors are present.

In some cases, a status code 410 Gone can be resolved by the visitor clearing their browser cache to force a fresh request. If this method does not yield a successful outcome, it unfortunately indicates that the operator has permanently deleted the relevant page. However, if it is publicly accessible content, it can still be accessed through non-profit projects like the Wayback Machine, which regularly index large parts of the internet and archive websites on their own servers.
