I’m able to see 18.104.22.168 without any issues. I can ping it, hit the https site and get DNS. All of those are caught what appears to be a drop at 22.214.171.124.
A simple traceroute from my system shows this IP is the final hop from me to 126.96.36.199, and also the last hop to 188.8.131.52 before getting consistent timeouts. Suggesting either packets being intentionally firewalled [via drop] or a routing issue.
Below URL suggests the IPv6 would also not work for me, though my ISP doesn’t provide me an ipv6 block with which to assign all of my internal systems.
