Hello dland01,
Thanks for the question about “sleeping” your website. If you are using BoldGrid, then your website is using WordPress. If you really want to make your site non-accessible, then I would advise on using a “maintenance mode” plugin. You can find an explanation and examples of these plugins here. If you are trying to retain the domain name or any search rankings, I would not recommend taking the site offline. You should use information from statistics programs to determine how people are visiting the website. If you see that you’re not getting people visiting your website, then it may require some advertising to let people know of its availability. Additionally, you may want to speak with a web developer/online marketing specialist if the problem is more of content or getting people engaged with your site.
I hope that helps to answer your question! If you require further assistance please let us know!
Regards,
Arnel C.
