I feel like the classic East Dakota reply would be that cloud flare CDN does not host your data and merely proxies it (bonus points if he uses the words "mere conduit" in his reply and therefore cloud flare can't be held responsible yada yada).

Jokes aside, as far as I can tell, https://downdetectorsdowndetector.com/ is NOT using Cloudflare CDN/Proxy

https://downdetectorsdowndetector.com/ is NOT using Cloudflare SSL

However, selesti reports it uses cloudflare DNS?

https://checkforcloudflare.selesti.com/?q=https://downdetect...

https://downdetectorsdowndetector.com/ is using Cloudflare DNS!

Checked 8 global locations, found DNS entries for Cloudflare in 3

Found in: England, Russia, USA

Not found in: China, Denmark, Germany, Spain, Netherlands

That won’t be an issue though - as we all know, DNS is rarely related to cloud failures
