I live next to Gert. Should I go over and "shake his hands"… ;)
But seriously, this seems to be a problem introduced by XS4all. Is there
anything we can/should do about?

> > Hello XS4All Noc,
> > We are Host Virtual, a cloud provider that provides dual-stack IPv4+IPv6 services worldwide in 10 locations via AS36236 and AS42210.
> > It has come to our attention that customers in any of our three EU locations, using our RIPE assigned ip space (2a00:dd80::/32) are unable to access the XS4all network, including sites such as www.python.org. We announce at a minimum, a /48 from each location as per generally accepted standards for IPv6 routability.
> > In previous communication with our peers, we've learned that XS4ALL filters its IPv6 traffic based on the strict case at http://www.space.net/~gert/RIPE/ipv6-filters.html published by Gert Döring.
> > While we understand and appreciate there has been much discussion on the topic we feel this type of strict filtering, based on rules published and not updated over 3 years ago are now negatively impacting both XS4ALL's own customers, and the end users of high profile sites such as www.python.org.
> > Being a supporter of many open source projects ourselves, and a strong supporter of moving IPv6 forward we appeal to you to review this policy. With IPv6 adoption now accelerating it's in all of our best interests to ensure IPv6 routability.
> > I appreciate your attention and review of this policy and have included relevant parties on the CC.
