Returning users return to cached site after shutting down Netlify site and changed registrar DNS records

I’m having an issue where returning issues are still seeing the cached netlify site, even after shutting down the netlify site. The domain is https://promu.io

  1. I deleted all records off Netlify DNS
  2. Turned off custom domains
  3. Went into namecheap and changed the DNS records to point to the new address
  4. Waited over 72 hrs

Is anyone else experiencing this? Can anyone please help?

@carpedn Nothing in your DNS points to Netlify and your files are not being served from Netlify, so this isn’t a Netlify issue. Have you tried clearing your cache with Cloudflare?
