Hi,
If a domain’s nameservers get changed from and no longer point to Cloudflare then after 7 days the domain gets automatically removed from Cloudflare.
I believe there should be a change made so when the following email is sent, it should also provide an exported copy of the sites settings, specifically DNS records + Firewall Rules + Rules as most custom changes can be made to them compared to most other options which are usually toggles or have limited options.
[Cloudflare]: The nameservers for website.com no longer point to Cloudflare
It can easily be attached as a txt or csv file to allow individuals to restore the domain at a later date if it was a mistake/error.
Kind Regards
