Hi I raised a ticket due to high packet loss when pinging my POP's gateway and was told that it's a "remote problem" which on further probing seemed to mean that it's an IPv4 problem - which I'm failing to see / understand. Backing up a bit... Since around 08:00 this morning I'm seeing significant, sustained packet loss when I ping my POP's (IPv6) gateway. The loss currently is trending at 18% but seems to be creeping up. If you visit <http://f8lure.mouselike.org/index.asp?DoAction=ViewHost&HostName=ipv6.ldml.com> you can see the issue. That URL has links to historic graphs which show that the packet loss increased markedly around 20:00 / 22:00 last night (2012-02-05), came back for a little while but subsequently has been consistently bad since around 08:00. Comparisons to IPv4 traffic can be seen at <http://f8lure.mouselike.org/index.asp?DoAction=ViewHost&HostName=78.105.5.204>. This shows little packet loss. FWIW, my provider, Be*, has had some significant issues in the recent past but these seem to have been addressed. Be* always have denied any sort of traffic shaping - but maybe that kicked in this morning? When I ping the POP's IPv4 address I see no packet loss. Pinging the external interface of my IPv6 router, I see no packet loss. So IPv6 traffic _only_ is being affected somewhere between my external IPv6 interface and the POPs gateway. It a recent issue which appeared, disappeared and then re-appeared with no changes being made this end. I do not know how to narrow down the problem further so that I can resolve the problem and would appreciate any pointers / ideas. TIA Simon
