[Opendnssec-user] Website wiki IPv6 issue?

[Mike]

Hi,

When I visit www.opendnssec.org, everything is fine.

But when I visit wiki.opendnssec.org, I notice some IPv6 issues.  Happy
Eyeballs, a.k.a., fast fallback, seems to workaround the problem, but
only satisfactorily.

What I see:

If I ping the wiki.opendnssec.org IPv6 address, I get a response.  If I
try to telnet to port 80 of the IPv6 address, it times out.

The IPv4 address works fine in both cases.

IPv6:  2001:610:188:149:145:100:190:51
IPv4:  145.100.190.51


Is there a known problem with IPv6 and the wiki?
