Apologies for bothering the list, but we have had tickets open with both parties without resolution. For the last few weeks, we have been seeing performance issues between sprint and uunet. We have not been able to determine anything which would be unique about our configuration. The symptoms are a 400ms latency between Sprint and UUnet routers and a 25% packet loss. An example trace fragment is: 2 Serial4-1-1.GW1.BOS1.ALTER.NET (157.130.4.25) 6.810 ms 9.343 ms 10.909 ms 3 123.ATM2-0.XR1.BOS1.ALTER.NET (146.188.176.226) 11.137 ms 10.868ms 17.13 5 ms 4 191.ATM3-0.XR1.EWR1.ALTER.NET (146.188.176.133) 22.651 ms 21.483ms 14.98 8 ms 5 193.ATM1-0-0.BR1.EWR1.ALTER.NET (146.188.176.49) 12.580 ms12.849 ms 16.1 78 ms 6 sl-pen-11-h3.sprintlink.net (137.39.44.130) 434.196 ms 432.565ms 438.700 ms 7 sl-bb11-pen-0-1.sprintlink.net (144.232.5.9) 451.170 ms 464.872ms 426.18 1 ms 8 sl-bb12-pen-10-0.sprintlink.net (144.232.5.158) 488.077 ms * 419.564 ms 9 sl-bb11-fw-3-0.sprintlink.net (144.232.8.157) 444.772 ms 462.465ms 457.6 47 ms 10 sl-gw15-fw-8-0-0.sprintlink.net (144.232.11.82) 499.928 ms476.629 ms 481 .154 ms Is anyone else seeing this? thanks! fletcher
