Last night I saw an issue with connectivity between a domestic site in Pennsylvania off of Level3's network connecting to a site on UUNet in Australia - latency was almost triple of what it normally is... Level3's response was of course "We don't see anything" - even with traceroutes showing otherwise. Did anyone else experience anything or hear anything about it? Latency is normally in the ~240ms range. 1 Loopback0.GW1.SYD2.Alter.Net (210.80.0.54) 4 msec 4 msec 4 msec 2 321.at-3-0-0.XR1.SYD2.Alter.Net (210.80.3.89) 8 msec 8 msec 4 msec 3 so-3-0-0.TR2.SYD2.Alter.Net (210.80.48.145) 4 msec so-3-0-0.TR1.SYD2.Alter.Net (210.80.48.133) 4 msec 4 msec 4 0.so-5-0-0.IR1.SAC2.Alter.Net (210.80.49.150) 164 msec 0.so-1-0-2.IR2.SAC2.Alter.Net (210.80.50.142) 164 msec 0.so-5-0-0.IR1.SAC2.Alter.Net (210.80.49.150) 164 msec 5 POS2-0.IR2.SAC1.ALTER.NET (137.39.31.206) 156 msec 156 msec POS2-0.IR1.SAC1.ALTER.NET (137.39.31.190) 164 msec 6 0.so-0-0-0.TL1.SAC1.ALTER.NET (152.63.0.114) 184 msec 180 msec 0.so-4-1-0.TL2.SAC1.ALTER.NET (152.63.0.118) 156 msec 7 0.so-7-0-0.XL1.SAC1.ALTER.NET (152.63.53.249) 172 msec 0.so-7-0-0.XL2.SAC1.ALTER.NET (152.63.54.9) 168 msec 164 msec 8 POS6-0.BR5.SAC1.ALTER.NET (152.63.52.225) 168 msec POS7-0.BR5.SAC1.ALTER.NET (152.63.52.229) 156 msec 156 msec 9 atm3-0.core2.SanFrancisco1.Level3.net (166.90.50.133) 496 msec 496 msec 492 msec 10 so-4-1-0.mp2.SanFrancisco1.Level3.net (209.247.10.237) 492 msec 500 msec 492 msec 11 so-0-1-0.mp1.Philadelphia1.Level3.net (64.159.0.141) 572 msec 572 msec 564 msec 12 gig10-2.hsa1.Philadelphia1.level3.net (209.247.9.26) 560 msec 560 msec 564 msec 13 unknown.Level3.net (63.209.178.162) 560 msec 556 msec 556 msec 3 ge-6-1-0.mp2.Philadelphia1.level3.net (64.159.3.29) [AS 3356] 4 msec 4 msec 4 msec 4 unknown.Level3.net (209.247.8.66) [AS 3356] 8 msec 4 msec 8 msec 5 unknown.Level3.net (64.159.17.166) [AS 3356] 8 msec 4 msec 8 msec 6 102.ATM2-0.BR3.NYC8.ALTER.NET (209.244.160.162) [AS 3356] 8 msec 8 msec 8 msec 7 0.so-6-1-0.XL2.NYC8.ALTER.NET (152.63.19.50) [AS 3356] 4 msec 8 msec 8 msec 8 0.so-1-0-0.TL2.NYC8.ALTER.NET (152.63.0.169) [AS 3356] 8 msec 0.so-2-0-0.TL2.NYC8.ALTER.NET (152.63.0.185) [AS 3356] 8 msec 8 msec 9 0.so-2-0-0.TL2.SAC1.ALTER.NET (152.63.8.2) [AS 3356] 464 msec 460 msec 456 msec 10 0.POS6-0.IR2.SAC1.ALTER.NET (152.63.0.117) [AS 3356] 464 msec 0.POS6-0.IR2.SAC1.ALTER.NET (152.63.0.149) [AS 3356] 80 msec 0.POS6-0.IR2.SAC1.ALTER.NET (152.63.0.117) [AS 3356] 468 msec 11 so-7-1-0.IR2.SAC2.ALTER.NET (137.39.31.209) [AS 3356] 468 msec 472 msec 468 msec 12 so-3-0-0.TR2.SYD2.Alter.Net (210.80.48.145) [AS 3356] 628 msec 0.so-1-0-0.TR2.SYD2.Alter.Net (210.80.50.141) [AS 3356] 624 msec so-3-0-0.TR2.SYD2.Alter.Net (210.80.48.145) [AS 3356] 644 msec 13 so-6-2-0.XR1.SYD2.Alter.Net (210.80.48.146) [AS 3356] 628 msec 624 msec 624 msec 14 311.ATM5-0-0.GW1.SYD2.Alter.Net (210.80.3.90) [AS 3356] 620 msec 616 msec 608 msec David Temkin Susquehanna International Group, LLP IMPORTANT:The information contained in this email and/or its attachments is confidential.
