    Make a static copy of the website

    If you have decided to take your website offline, it is worth keeping a static copy of your website online. This will allow both the users and the Googlebot to still access the majority of the content on your pages. This will also avoid your site from being deindexed.

    Point DNS to the static copy

    Make sure that the DNS address points to this static copy of the website.

    Use Same URLs

    By using the same URLs, you will still be able to retain your rankings in Google Search once your website is live again.

    It is important to note that this approach will not work for all types of websites.

Till the issue is fully resolved, the best solution is to take your website offline, especially the pages that contain critical and confidential information.
