I have an update on this issue. I was so blunt and opened a ticket for
an IP-Plus customer, claiming that they could not access www.swisscom.ch
over IPv6.

It took some time and at least three second-level supporters until
someone within IP-Plus found someone from the webserver team who knew
who was managing that load-balancer and now IPv6 seems to work again. I
have yet to receive an official confirmation that the issue is
permanently solved. Maybe they'll share the root cause of the issue but
I doubt it.

Best Regards and thank again to all who gave insights into those
technical details within tcpdump.

Jean-Pierre
