Getting there is hit or miss. Sometimes just shows a background image sometimes I get "integrishealthandme.com took too long to respond." On FIOS too using Google DNS so not a Cox problem. Tried changing from google DNS to Cloudflare DNS, no change. Tried disabling IPv6. No change. My guess is they changed their site and it hasn't propagated yet. I tried looking for the Whois contact but it's masked. I suggest trying from a VPN. Used Opera GX VPN and it worked.

That's why I suggested they do a flushdns. It appears to have propagated but if their cache is holding on tot he old info, they could have an issue. I was able to use chrome, edge, safari and opera, (with and without internal vpn) without issue from here in Va.
