Some IPv6 Routing not working via goscomb.net
[gb] Shadow Hawkins on Saturday, 16 October 2010 12:20:57
Is there a problem with goscomb routing at the moment? I can get to some IPv6 sites (sixxs, google, kame.net), but others like ipv6-speedtest.net fail. Doing a traceroute the problem sites keep bouncing between two machines in goscomb's network, see below:
Tracing route to ipv6-speedtest.net [2a02:68:1::3] over a maximum of 30 hops: 1 3 ms 3 ms 3 ms firewall.tellytart.co.uk [2a01:348:250::1] 2 26 ms 22 ms 18 ms gw-938.lon-02.gb.sixxs.net [2a01:348:6:3a9::1] 3 63 ms 25 ms 32 ms ae0-1235.rt2.the.uk.goscomb.net [2a01:348:0:4:0:3:0:1] 4 20 ms 24 ms 28 ms ae0-1624.rt0.sov.uk.goscomb.net [2a01:348::13:1:1] 5 37 ms 20 ms 20 ms ge-0-0-47.cs0.sov.uk.goscomb.net [2a01:348::17:1:1] 6 20 ms 19 ms 40 ms ae0-62.rt0.sov.uk.goscomb.net [2a01:348::17:0:1] 7 20 ms 52 ms 19 ms ge-0-0-47.cs0.sov.uk.goscomb.net [2a01:348::17:1:1] 8 20 ms 19 ms 30 ms ae0-62.rt0.sov.uk.goscomb.net [2a01:348::17:0:1] 9 24 ms 21 ms 24 ms ge-0-0-47.cs0.sov.uk.goscomb.net [2a01:348::17:1:1] 10 19 ms 19 ms 20 ms ae0-62.rt0.sov.uk.goscomb.net [2a01:348::17:0:1] 11 27 ms 19 ms 25 ms ge-0-0-47.cs0.sov.uk.goscomb.net [2a01:348::17:1:1] 12 21 ms 21 ms 58 ms ae0-62.rt0.sov.uk.goscomb.net [2a01:348::17:0:1]
A working site gives:

That IP is unreachable from a variety of locations, nothing much we can do about as we are not the transit provider for the remote site.
