Trying to troubleshoot packet loss from NYC to DEU. Traceroute shows: tdurack@2ua82715mg:~$ traceroute -I 194.25.250.73 traceroute to 194.25.250.73 (194.25.250.73), 30 hops max, 60 byte packets <snip> 4 216.55.2.85 (216.55.2.85) 1.694 ms 1.698 ms 1.698 ms 5 vb1010.rar3.nyc-ny.us.xo.net (216.156.0.17) 4.788 ms 4.792 ms 4.791 ms 6 207.88.14.178.ptr.us.xo.net (207.88.14.178) 1.684 ms 1.461 ms 1.452 ms 7 62.157.250.245 (62.157.250.245) 40.457 ms 42.980 ms 42.982 ms 8 hh-eb3-i.HH.DE.NET.DTAG.DE (62.154.32.134) 129.417 ms * 129.422 ms 9 194.25.250.73 (194.25.250.73) 139.501 ms 136.192 ms 139.236 ms Packet loss of approx. 20% affects hops 7 and 8, along with end host 9. Loss appears to be data-plane, not control-plane rate limiting. Affected customer confirms this too :-) 62.157.250.245 is in Deutsche Telekom address spaces, so I'm guessing this is either a DTAG problem or an issue between XO and DTAG. I have a ticket open with XO, but I'm having a hard time figuring out what is ~40ms away from NYC on a path to DEU. Any idea what the physical path is? -- Tim:>
