Recent post are not visible in my site?

hello today i deleted one of my post and rewrite the post and upload but my old post is showing instead of showing new one. my hosting provider said that its problem aa=rising from Cloudflare account. now any newer posts are not showing in my website. can i know if this problem is arising from here and how much time does really take to fix this issue?

I would check your cache settings as the post information maybe cached still.
