Hi, I have been trying to get a hold of someone who looks after ASN 7160 since last Thursday both directly (OrgTechEmail), and indirectly via upstreams with no luck. I am trying to resolve or at least understand a routing reachability issue between our two networks. It seems packets from ASN7160 are not able to get back to some of my netblocks in AS 11647. e.g. eg. this is fine % traceroute -q1 -s 98.159.240.105 -Picmp 68.233.77.173 traceroute to 68.233.77.173 (68.233.77.173) from 98.159.240.105, 64 hops max, 72 byte packets 1 cogent-vl38-tor-hespler-v38 (205.211.165.117) 0.091 ms 2 gi1-18.mag02.yyz02.atlas.cogentco.com (38.104.158.77) 0.701 ms 3 te0-7-0-12.ccr22.yyz02.atlas.cogentco.com (154.54.40.165) 0.765 ms 4 be2080.ccr42.ord01.atlas.cogentco.com (154.54.42.5) 15.871 ms 5 be2003.ccr21.ord03.atlas.cogentco.com (154.54.29.22) 17.882 ms 6 38.104.102.102 (38.104.102.102) 17.395 ms 7 border2.te7-1-bbnet1.chg004.pnap.net (64.94.32.19) 16.335 ms 8 oraclebol-7.border2.chg004.pnap.net (74.217.8.106) 16.945 ms 9 VIP-CH-77-173.taleo.net (68.233.77.173) 17.014 ms This is not % traceroute -q1 -s 205.211.165.119 -Picmp 68.233.77.173 traceroute to 68.233.77.173 (68.233.77.173) from 205.211.165.119, 64 hops max, 72 byte packets 1 cogent-vl38-tor-hespler-v38 (205.211.165.117) 0.145 ms 2 gi1-18.mag02.yyz02.atlas.cogentco.com (38.104.158.77) 7.926 ms 3 te0-7-0-12.ccr22.yyz02.atlas.cogentco.com (154.54.40.165) 1.081 ms 4 be2080.ccr42.ord01.atlas.cogentco.com (154.54.42.5) 15.699 ms 5 be2003.ccr21.ord03.atlas.cogentco.com (154.54.29.22) 15.394 ms 6 * 7 * 8 * Same with 64.7.137.0/24 and 64.7.135.0/24 for some reason, but not all subnets within 64.7.128.0/19 are blocked. % traceroute -q1 -s 64.7.135.1 -Picmp 68.233.77.173 traceroute to 68.233.77.173 (68.233.77.173) from 64.7.135.1, 64 hops max, 60 byte packets 1 iolite3 (199.212.135.73) 0.234 ms 2 cogent-vl108 (67.43.129.246) 2.575 ms 3 gi1-18.mag02.yyz02.atlas.cogentco.com (38.104.158.77) 2.844 ms 4 te0-7-0-12.ccr21.yyz02.atlas.cogentco.com (154.54.40.137) 3.460 ms 5 be2079.ccr41.ord01.atlas.cogentco.com (154.54.27.181) 17.338 ms 6 be2005.ccr21.ord03.atlas.cogentco.com (66.28.4.74) 17.962 ms 7 * vs % traceroute -q1 -s 64.7.138.225 -Picmp 68.233.77.173 traceroute to 68.233.77.173 (68.233.77.173) from 64.7.138.225, 64 hops max, 60 byte packets 1 iolite3 (199.212.135.73) 0.193 ms 2 cogent-vl108 (67.43.129.246) 2.210 ms 3 gi1-18.mag02.yyz02.atlas.cogentco.com (38.104.158.77) 2.469 ms 4 te0-7-0-12.ccr22.yyz02.atlas.cogentco.com (154.54.40.165) 3.091 ms 5 be2080.ccr42.ord01.atlas.cogentco.com (154.54.42.5) 17.566 ms 6 be2003.ccr21.ord03.atlas.cogentco.com (154.54.29.22) 18.457 ms 7 38.104.102.102 (38.104.102.102) 17.831 ms 8 border2.te8-1-bbnet2.chg004.pnap.net (64.94.32.83) 22.324 ms 9 oraclebol-7.border2.chg004.pnap.net (74.217.8.106) 19.091 ms 10 VIP-CH-77-173.taleo.net (68.233.77.173) 20.318 ms The issue started around July 3rd some time.
