Is something dropping off the net? some time ago i sent an email to the list telling that we have a very congested 12 Mbits link to the US, it still are, and will be until the OC3 get up and running. To all the ASs that peer directly with us here in Brazil, our server is the best one and appears to solve the problem very well to regions of the net not so well connected to the core like ours. This is our verification of one of the auth servers for COM.BR located outsided of Brazil, just for time comparing. http://registro.br/stat/ns/nsvixcom.html bash> traceroute ns-ext.vix.com traceroute to ns-ext.vix.com (204.152.184.64), 30 hops max, 40 byte packets 1 gw.REGISTRO.BR (143.108.23.1) 0.159 ms 0.132 ms 0.126 ms 2 fe010-core.spo.ansp.br (143.108.13.65) 0.546 ms 0.404 ms 0.401 ms 3 166.49.29.201 (166.49.29.201) 576.024 ms * 727.498 ms 4 core2.WestOrange.cw.net (204.70.4.185) 792.518 ms 743.608 ms 650.876 ms 5 cw-ip-eng-interconnects.WestOrange.cw.net (204.70.1.38) 888.656 ms 883.417 ms 937.981 ms 6 nynap.above.net (192.157.69.64) 751.384 ms 935.749 ms 1543.965 ms 7 iad-penn-oc3.iad.above.net (209.249.0.49) 798.519 ms 741.973 ms 747.353 ms 8 * core1-core3-oc48.iad.above.net (209.249.203.34) 814.138 ms 694.633 ms 9 sjc2-iad-oc48.sjc2.above.net (216.200.127.26) 877.041 ms 846.111 ms 726.771 ms 10 mibh-above-1.mibh.net (208.184.102.10) 847.176 ms 443.224 ms 825.496 ms 11 head7.pla.mibh.net (128.177.255.21) 1109.885 ms 1411.469 ms 661.921 ms 12 pla1b.feed1.pla.mibh.net (204.152.184.211) 616.937 ms 711.377 ms 584.922 ms 13 ifw2-core.pa.vix.com (204.152.184.5) 778.297 ms 725.023 ms 856.954 ms 14 * ns-ext.vix.com (204.152.184.64) 802.943 ms 863.011 ms Fred > > kre > -- Frederico A C Neves Registro .br - R.Pio XI, 1500 +55 11 3838-4130 São Paulo, SP, Brazil - 05468-901
