It took very long for hop 11 and 12, and then finished to the end right
It is just because traceroute waited for the reply with N seconds timeout,
then retried twice.
Three asterisk just means that a router does not issue
ICMP time exceeded messages.
I do know what the asterisks means in traceroute. I do have them
on my IPv4 only cable connection, as they are using private IP
addresses in their backbone (and I do filter them on my host).
But usually it does not take that long, as it has taken to your
host. Maybe this is different in IPv6...
Here an other example with duration:

And to your IPv6 host (in this run it hung right after the 10
hop, without even starting to display the 11 for much longer then
just a few seconds):

The most of this 12+ minutes was used for hop 11 + 12, compared
to the above IPv4 traceroute which had 3 hops with asterisks and
only 50 seconds, it is quite long...
PS: No need to use "reply all", reply only to the list is
perfect, as I do filter e-mails based on the "List-Id" header line.
