Duplicity website

Hello,
I have website: https://www.krasneplaze.cz/ and now i find this: https://d1vvjmpwksefjn.cloudfront.net/

Is this duplication due Cloudflare or not? And why.

Thank you for answer.

Thats Cloudfront, not Cloudflare. If there is an issue with that site you’d have to contact Amazon, as they are hosting that.
