Hello,
There has been at least a 25% packet loss between hetzner.de and cox.net in the last couple of hours.
Tried contacting hetzner.de, but they said it's not on their network. This has already happened a couple of days ago, too (strangely, on April 1), but then was good for the rest of the week -- no problems whatsoever.
I wouldn't really care about this, if not for ssh: it just doesn't work on such huge loss.
No other routes or networks seem affected.
Any advice?
Doesnt looks like tinet for me.
Might have been eurorings.net, as your Amazon EC2 to Hetzner traceroute seemed to suggest? This loss was apparent even with their own main websites: cox.net from a hetzner.de node: # mtr --report{,-wide,-cycles=60} --order "SRL BGAWV" cox.net ; date ... 3.|-- hos-bb2.juniper4.rz2.hetzner.de 60 60 0.0% 2.7 3.5 5.8 62.5 10.1 4.|-- r1nue1.core.init7.net 60 60 0.0% 2.8 4.2 5.2 13.5 3.8 5.|-- r1nue2.core.init7.net 60 60 0.0% 2.9 4.7 6.0 28.7 5.0 6.|-- r1fra2.core.init7.net 60 60 0.0% 5.7 7.4 8.1 15.9 3.6 7.|-- r1fra1.core.init7.net 60 60 0.0% 5.9 7.6 8.1 16.8 3.2 8.|-- xe-4-2-2.fra23.ip4.tinet.net 60 60 0.0% 5.9 6.4 7.1 36.2 5.6 9.|-- xe-9-0-0.was14.ip4.tinet.net 60 43 28.3% 142.3 145.0 145.2 190.0 9.6 10.|-- cox-communications-gw.ip4.tinet.net 60 48 20.0% 124.8 129.6 130.2 176.6 13.2 11.|-- dukedsrj02-ge210.0.rd.at.cox.net 60 45 25.0% 137.7 141.2 141.6 194.7 11.6 12.|-- 68.1.15.238 60 49 18.3% 138.1 138.7 138.7 140.0 0.4 13.|-- 68.99.123.4 60 36 40.0% 140.4 140.9 140.9 141.6 0.3 14.|-- ww2.cox.com 60 44 26.7% 140.6 140.9 140.9 141.8 0.3 Fri Apr 5 18:19:21 PDT 2013 hetzner.de from a cox.net node: ... 5.|-- COX-68-12-8-132-static.coxinet.net 60 60 0.0% 11.6 15.3 15.8 35.1 4.9 6.|-- 68.1.5.161 60 60 0.0% 55.7 59.8 60.0 95.8 5.3 7.|-- nyk-s2-rou-1001.US.eurorings.net 60 60 0.0% 55.8 63.8 64.9 139.4 14.7 8.|-- nntr-s1-rou-1101.FR.eurorings.net 60 60 0.0% 149.8 154.1 154.1 171.9 4.3 9.|-- kehl-s2-rou-1103.DE.eurorings.net 60 60 0.0% 147.2 152.8 153.1 206.1 8.7 10.|-- ffm-s1-rou-1102.DE.eurorings.net 60 60 0.0% 143.3 147.7 147.7 177.2 5.0 11.|-- nbg-s1-rou-1001.DE.eurorings.net 60 60 0.0% 147.3 153.8 154.0 211.1 10.0 12.|-- kpn-gw.hetzner.de 60 44 26.7% 173.3 177.6 177.6 184.5 2.7 13.|-- hos-bb2.juniper3.rz2.hetzner.de 60 42 30.0% 170.3 175.1 175.2 203.1 5.6 14.|-- hos-tr4.ms-ex3k2.rz1.hetzner.de 60 44 26.7% 171.9 175.9 175.9 185.4 2.8 15.|-- www.hetzner.de 60 42 30.0% 170.4 175.1 175.2 187.0 4.1 Fri 5 Apr 2013 17:38:11 PDT ... 5.|-- COX-68-12-8-132-static.coxinet.net 60 60 0.0% 11.3 14.2 14.5 33.6 3.3 6.|-- 68.1.5.161 60 60 0.0% 56.2 61.1 61.8 135.6 11.6 7.|-- nyk-s2-rou-1001.US.eurorings.net 60 60 0.0% 56.0 60.6 61.0 121.1 8.7 8.|-- nntr-s1-rou-1101.FR.eurorings.net 60 58 3.3% 150.1 153.5 153.5 166.3 2.8 9.|-- kehl-s2-rou-1103.DE.eurorings.net 60 29 51.7% 147.5 152.0 152.1 170.8 5.3 10.|-- ffm-s1-rou-1102.DE.eurorings.net 60 28 53.3% 143.7 148.4 148.6 186.7 8.0 11.|-- nbg-s1-rou-1001.DE.eurorings.net 60 60 0.0% 147.2 151.8 151.9 178.2 4.7 12.|-- kpn-gw.hetzner.de 60 45 25.0% 172.7 177.0 177.0 197.4 4.0 13.|-- hos-bb2.juniper3.rz2.hetzner.de 60 41 31.7% 170.4 176.5 176.6 190.9 6.2 14.|-- hos-tr4.ms-ex3k2.rz1.hetzner.de 60 50 16.7% 171.8 175.6 175.6 183.1 2.8 15.|-- www.hetzner.de 60 47 21.7% 170.5 174.2 174.3 188.8 3.2 Fri 5 Apr 2013 19:22:36 PDT But it has since subsided: ... 3.|-- hos-bb2.juniper4.rz2.hetzner.de 60 60 0.0% 2.7 2.9 3.4 41.4 5.0 4.|-- r1nue1.core.init7.net 60 60 0.0% 2.8 5.2 6.3 12.4 3.8 5.|-- r1nue2.core.init7.net 60 60 0.0% 2.9 4.0 4.7 14.0 3.2 6.|-- r1fra2.core.init7.net 60 60 0.0% 5.7 7.7 8.4 17.0 3.9 7.|-- r1fra1.core.init7.net 60 60 0.0% 5.9 8.7 9.3 17.1 3.7 8.|-- xe-4-2-2.fra23.ip4.tinet.net 60 60 0.0% 5.9 6.1 6.2 15.0 1.3 9.|-- xe-9-0-0.was14.ip4.tinet.net 60 60 0.0% 95.9 99.4 99.8 134.3 8.9 10.|-- cox-communications-gw.ip4.tinet.net 60 60 0.0% 100.0 100.5 100.5 104.0 0.6 11.|-- dukedsrj02-ge210.0.rd.at.cox.net 60 60 0.0% 113.2 116.7 117.1 163.6 10.9 12.|-- 68.1.15.238 60 60 0.0% 113.4 113.8 113.8 116.0 0.4 13.|-- 68.99.123.4 60 50 16.7% 115.6 115.9 115.9 116.6 0.2 14.|-- ww2.cox.com 60 59 1.7% 115.7 116.1 116.1 117.2 0.3 Fri Apr 5 19:46:48 PDT 2013 ... 5.|-- COX-68-12-8-132-static.coxinet.net 60 60 0.0% 11.5 16.2 16.8 57.0 6.1 6.|-- 68.1.5.161 60 60 0.0% 56.3 61.5 61.8 105.1 6.5 7.|-- nyk-s2-rou-1001.US.eurorings.net 60 60 0.0% 56.6 63.9 64.6 122.2 11.0 8.|-- nntr-s1-rou-1101.FR.eurorings.net 60 60 0.0% 150.4 157.6 158.0 226.0 11.8 9.|-- kehl-s2-rou-1103.DE.eurorings.net 60 60 0.0% 147.7 152.5 152.7 206.0 7.7 10.|-- ffm-s1-rou-1102.DE.eurorings.net 60 60 0.0% 143.6 150.4 150.5 184.4 7.6 11.|-- nbg-s1-rou-1001.DE.eurorings.net 60 60 0.0% 147.7 154.6 155.2 261.1 15.2 12.|-- kpn-gw.hetzner.de 60 60 0.0% 148.0 153.1 153.2 175.2 4.2 13.|-- hos-bb2.juniper3.rz2.hetzner.de 60 60 0.0% 145.0 164.8 166.2 220.6 22.2 14.|-- hos-tr4.ms-ex3k2.rz1.hetzner.de 60 59 1.7% 145.8 152.5 152.6 166.7 4.4 15.|-- www.hetzner.de 60 58 3.3% 144.5 149.7 149.7 161.3 3.9 Fri 5 Apr 2013 20:53:59 PDT With the end-to-end working, too.
