Connect a SiteDu.de Domain #
To keep things simple, we usually don’t give access to the DNS settings of your domain. So if you want to connect a domain you have purchased on SiteDu.de, simply reach out to us and we will activate it for your website. Please note that the complete transfer of the website name may take up to 48 hours. This timeline is determined by the domain registrar’s processing times and is beyond our control. Thank you for your understanding and patience during this transition as we work to launch your site smoothly. In the meantime, you can build and work on the website on the existing subdomain.
