Routing problems to www.eurovision.tv 2400:CB00::/32 CLOUDFLARE

[Chris Welti]

This could be because there is no covering 2400:CB00::/32 route by Cloudflare in the global IPv6 routing table.
There is only 2400:CB00:2048::/48 and this might be filtered by ISPs due to the APNIC miniumum allocation size of /32 for 2400::/12.
Cloudflare must announce at least the covering /32 for it to be globally reachable.
