What happens when a domain is blocked?

Hello.

Can you explain how domain name blocking works? I understand that certain services can block a domain, and search engines can also remove it from their results.

I have a few questions:

1. If a domain is named bla.fr but redirects to bla.bla.fr (a subdomain) where the actual content resides, can the domain still be blocked even though it is just a redirect?

2. If the main domain is blocked, will this have any impact on the subdomain?

3. If a domain is sanctioned or blocked by certain services or search engines, will it still function as a redirect or will it be completely unavailable? I recall a large website being blocked but continuing to redirect to another domain where it was still accessible despite the initial block.

1. In my opinion, a domain can still be blocked even if it is just a redirect or if there is content present on it. This would depend on whether or not it has been added to the list of banned addresses.
2. It is difficult to say for certain whether blocking the main domain would have any impact on the subdomain. From what I have seen, some sites have been blocked but continued to work without issue.
3. I believe that a domain that has been sanctioned or blocked by certain services or search engines would still function as a redirect. For example, some large torrent trackers have been blocked but still redirect users to mirrors. However, this information should be verified as I cannot say for certain.

It is clear that if a copyright holder files a complaint against your website and you fail to remove the infringing content within 24 hours, your website may be blocked. In order to resolve this issue, you can contact your hosting provider or registrar and request that they temporarily unblock your domain name for a short period of time, such as an hour, so that you can delete the content. If all else fails, you can block access to these pages in the .htaccess file and have the server give a 404 error code.

It should be noted that my personal experience involved being blocked by the provider rather than the registrar.

I can provide an explanation of how domain name blocking works and the various nuances involved.

1. Domain Blocking and Redirects:
When it comes to domain blocking, the focus is typically on the domain itself, rather than the specific subpages or content hosted on that domain. This means that if a domain, such as bla.fr, is blocked, the blocking will apply to the entire domain, including any subdomains or redirects associated with it.

In the case of a redirect from bla.fr to bla.bla.fr, the blocking is still effective. Even though the actual content resides on the subdomain, the initial domain (bla.fr) is the one that is being blocked. This means that any attempt to access bla.fr will be blocked, regardless of the redirect. The user will either be unable to reach the website or will be presented with an error message indicating that the domain is blocked.

2. Impact on Subdomains:
When a main domain is blocked, the impact on any associated subdomains can be significant. Domain blocking is often implemented at the top-level domain (TLD) or registrant level, which means that the entire domain structure, including all subdomains, can be affected.

If the bla.fr domain is blocked, the bla.bla.fr subdomain would also be subject to the same restrictions. Users attempting to access the subdomain would likely encounter the same blocking or error messages as they would when trying to access the main domain.

It's important to note that in some cases, subdomains may be treated separately from the main domain, but this depends on the specific blocking mechanisms and policies implemented by the blocking entity (e.g., search engines, internet service providers, or government agencies).

3. Functionality of Blocked Domains:
The impact on a blocked domain's functionality can vary depending on the nature of the blocking and the website owner's response strategies.

a. Complete Unavailability: In some cases, when a domain is blocked, it becomes completely inaccessible. Any attempt to access the domain will result in an error message or a failed connection, as the domain has been effectively taken offline or rendered inaccessible by the blocking entity.

b. Redirects and Circumvention: As you mentioned, there are instances where a blocked domain may still function as a redirect to another domain or location. This could be a deliberate strategy by the website owners to circumvent the blocking by redirecting users to an alternative, unblocked domain.

c. Selective Blocking: In certain cases, the blocking may be targeted at specific content or features on the website, rather than the entire domain. For example, the blocking may prevent access to certain pages or services, while allowing the rest of the website to remain accessible through redirects or alternative paths.

d. Temporary or Partial Blocking: The blocking may also be temporary or only partially effective, especially in cases where the blocking has not yet been fully propagated or updated across all relevant services and search engines. This can allow the redirect to still function for a limited time before the blocking is fully implemented.
