IPv6 routing problem. Who is responsible to fix this?

[luizcpj]

The website https://www.ripe.net/ is IPv6 enabled, but I can only access it by using IPv4 protocol. There seems to be a problem with IPv6 routing. Who is responsible to fix the problem?

From my native IPv6:

C:\Users\Junior>tracert www.ripe.net
