Only afterward, they will protect it with Cloudflare/Akamai/Cloudfront, etc, which means you'll have a DNS history trail to lookup.
I've had good luck with services such as SecurityTrails, Virustotal and CompleteDNS for DNS history.
Once you find the original A record IP address, you can put it in your hosts file, pointing to the domain. Then, you will be able to access the site, bypassing the CDN without issue.
