Hello,
sorry if this is not the right place to ask, I'm IPv6 newbie. I applied for an account and everything work great, but I'm not able to get to www.sixxs.net from my work machine - pckasparek.fit.vutbr.cz, 2001:718:802:1::14. I can see all other servers I tried, but not this one. I have used traceroute from this site and it ends after several hops, but from http://www.sixxs.net/tools/grh/dfp/ripe/, CESNET prefix seems fine. Here is traceroute from pckasparek -> www.sixxs.net:

so Telia -> CESNET seems to be affected. I have the same results from other boxes using that path, for example demuc02. You can run traces from most sixxs POPs at http://www.sixxs.net/tools/traceroute/
