So I was trying to browse the list of IETF mailing lists at
www.ietf.org
to see who might be interested in my failures to browse sites like
yahoo.com and netflix.com following the onset of World IPv6 Day.
Except that I can't browse www.ietf.org either.
It did work previously. I have a packet capture of the failing "telnet
www.ietf.org 80" session, if anyone is interested. It looks fine and
proper, all the expected SYNs and ACKs as I sent my HTTP request,
except for the failure to return any HTTP response. I'm running
FreeBSD 9.0-STABLE. 8.2-STABLE also fails the same way. No doubt you
can reach www.m5p.com over IPv6; it's been working for years.
Would one of you be able to tell me which mailing should I be using?
My apologies for the inappropriate message. -- George Mitchell

This sort of failure is usually a PMTUD failure. If you are using
a tunnel you need to ensure that your tunnel provider sends back
PTB's. The IETF servers do see the PTB's. www.ietf.org does work
over tunnels.
You can test this theory by lowering the local mtu using "route
change -inet6 :: -mtu 1280" (from memory). This will change the
advertised mss from 1440. "route -n get -inet6 ::" will show you
the current values.
Thanks very much -- your diagnosis is correct! Using
"route change -inet6 :: -mtu 1280" fixed the problem for www.ietf.org
and all the other sites I've been having problems with, too.
We now return you to your normal working group traffic. -- George
