The Looking Glass page is not maintained by Engineering. I did ask our Ops team to take a look into it, as we don't appear to be learning 2606:c380::/32 directly from 7843 and to ensure there are no other complaints about reachability to Google. There are a couple of issues relating to the return path and it definitely needs TWC's involvement to address so if your concern is about the return path, any response is likely to have TWC open a ticket. The last hop in your traceroute is where we hand it off to Google's backbone AS and the traffic enters and exits in NY as expected based on your mtr. To get back to you we use HE and you are reachable via ICMP. I can't speak to how the first starred hop in your mtr reaches you. I didn't bother sending a bunch of other trace routes which show things working, but from that last hop here is your return traceroute. traceroute inet6 2606:c380::1994 traceroute6 to 2606:c380::1994 (2606:c380::1994) from 2610:18::2071, 64 hops max, 12 byte packets 1 2610:18:10:1::2 (2610:18:10:1::2) 11.641 ms 1.184 ms 0.611 ms 2 twcable-backbone-as7843.10gigabitethernet2.switch1.nyc7.he.net (2001:470:0:2bd::2) 1.386 ms 0.628 ms 0.634 ms 3 2001:1998:0:4::105 (2001:1998:0:4::105) 6.064 ms 5.019 ms 2001:1998:0:4::394 (2001:1998:0:4::394) 4.840 ms 4 2001:1998:0:4::a2 (2001:1998:0:4::a2) 31.979 ms 29.301 ms 31.959 ms 5 2001:1998:0:8::2a5 (2001:1998:0:8::2a5) 43.977 ms 2001:1998:0:8::2a7 (2001:1998:0:8::2a7) 42.679 ms 2001:1998:0:8::2a5 (2001:1998:0:8::2a5) 42.380 ms 6 2604:6000:0:4::cd (2604:6000:0:4::cd) 40.389 ms 40.143 ms 40.418 ms 7 2604:6000:0:4:0:2006:0:21f1 (2604:6000:0:4:0:2006:0:21f1) 43.659 ms 42.356 ms 43.579 ms 8 2604:6000:0:4::f:156 (2604:6000:0:4::f:156) 28.867 ms 28.846 ms 28.924 ms 9 2604:6000:0:8::f:215 (2604:6000:0:8::f:215) 29.048 ms 28.992 ms 29.026 ms 10 * * * 11 * * * ^C {master}

If anyone has IPv6 eyes inside XO (their Looking Glass page doesn't support it), can you trace to 2606:c380::1994? I would appreciate it.

I suspect this is just me, but putting it out there. Coming from Time Warner Cable trying to reach Google, it dies inside XO. Anyone else seeing this?
