Level3 Routing Problems in Atlanta?

Thu Aug 6 06:02:16 UTC 2009

Starting a little closer and I'm seeing :

traceroute to 70.164.18.1 (70.164.18.1), 64 hops max, 52 byte packets
 1  ge-7-21.car1.Atlanta1.Level3.net (4.71.24.129)  0.393 ms  1.590 ms
1.492 ms
 2  ge-6-0-0-51.gar2.Atlanta1.Level3.net (4.68.103.7)  3.484 ms  3.981 ms

 3  COX-COMMUNI.gar2.Atlanta1.Level3.net (65.59.222.6)  14.860 ms  124.165

ms
 5  nova-gw.nova.org (70.164.18.1)  26.850 ms  34.466 ms  24.355 ms

Hop 4 seems a bit variable - sometimes it's there, sometimes it's not :
 3  COX-COMMUNI.gar2.Atlanta1.Level3.net (65.59.222.6)  10.614 ms  5.734 ms
15.114 ms
 4  * * *
 5  nova-gw.nova.org (70.164.18.1)  33.154 ms  27.222 ms  30.242 ms

Overall ping times to the host are jumping between 30ms and 130ms :

$ ping 70.164.18.1
