routing issue between RIPE Meeting and Tiscali/Occaid

[Gert Doering]

Hi,

is someone from Occaid (or with good contacts to them) around?

I'm at the RIPE meeting in Tallinn, and can't reach www.arin.net nor
www.occaid.net over IPv6.

>From looking at traceroutes, it seems that occaid has no route back
to the RIPE meeting network.

working route (from home):

...

(the web server doesn't answer traceroutes, but "ping" works)


non-working route, from Tallinn:

the next hop should be the occaid equinix router...

The RIPE meeting prefix is 2A01:80::/32 - so no arguments about
"more specifics are a bad idea" and similar...

Hmmm, inside Tiscali, the routing seems to be much worse for the 
RIPE meeting prefix - scenic route via japan...?  This is what GRH
tells me...

"looks ugly to me"


Given that I spent the days telling folks "yes, IPv6 works, please go
ahead and use it" I'd appreciate if you folks would actually make it
work :-)

thanks,
