I haven’t been able to connect to http://arin.net for several hours, but was able to open a ticket this morning. I’ve tried from several different networks, all roads seem to lead to the same place, with packets dropping at the NTT interface 129.250.196.154. e.g.: $ traceroute arin.net<http://arin.net> traceroute: Warning: arin.net<http://arin.net> has multiple addresses; using 199.43.0.44 traceroute to arin.net<http://arin.net> (199.43.0.44), 64 hops max, 52 byte packets 1 l100.lsanca-vfttp-106.verizon-gni.net<http://l100.lsanca-vfttp-106.verizon-gni.net> (98.112.74.1) 5.992 ms 4.865 ms 4.943 ms 2 172.102.106.24 (172.102.106.24) 9.962 ms 9.723 ms 12.242 ms 3 ae2-0.lax01-bb-rtr2.verizon-gni.net<http://ae2-0.lax01-bb-rtr2.verizon-gni.net> (130.81.22.238) 29.982 ms * so-4-1-0-0.lax01-bb-rtr2.verizon-gni.net<http://so-4-1-0-0.lax01-bb-rtr2.verizon-gni.net> (130.81.151.248) 9.428 ms 4 0.ae6.br1.lax15.alter.net<http://ae6.br1.lax15.alter.net> (140.222.225.137) 9.806 ms * * 5 ae-7.r01.lsanca20.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.8.85) 10.409 ms 0.ae6.br1.lax15.alter.net<http://ae6.br1.lax15.alter.net> (140.222.225.137) 19.783 ms 9.757 ms 6 ae-7.r01.lsanca20.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.8.85) 10.292 ms 9.357 ms 12.291 ms 7 ae-17.r01.lsanca07.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.4.207) 22.541 ms ge-101-0-0-3.r06.asbnva02.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.196.153) 72.412 ms ae-17.r01.lsanca07.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.4.207) 22.167 ms 8 ge-101-0-0-3.r06.asbnva02.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.196.153) 72.510 ms 74.590 ms 72.258 ms 9 ge-101-0-0-3.r06.asbnva02.us.ce.gin.ntt.net<http://us.ce.gin.ntt.net> (129.250.196.154) 69.960 ms * 70.930 ms 10 * * * 11 * * * $ traceroute www.arin.net<http://www.arin.net> traceroute: Warning: www.arin.net<http://www.arin.net> has multiple addresses; using 199.43.0.43 traceroute to www.arin.net<http://www.arin.net> (199.43.0.43), 64 hops max, 40 byte packets 1 router1.sb.becknet.com<http://router1.sb.becknet.com> (206.83.0.1) 1.010 ms 0.420 ms 0.536 ms 2 206-190-77-9.static.twtelecom.net<http://206-190-77-9.static.twtelecom.net> (206.190.77.9) 3.983 ms 0.732 ms 0.686 ms 3 64-129-238-182.static.twtelecom.net<http://64-129-238-182.static.twtelecom.net> (64.129.238.182) 2.760 ms lax2-pr2-xe-1-3-0-0.us.twtelecom.net<http://lax2-pr2-xe-1-3-0-0.us.twtelecom.net> (66.192.241.218) 2.816 ms 64-129-238-186.static.twtelecom.net<http://64-129-238-186.static.twtelecom.net> (64.129.238.186) 18.203 ms 4 4.68.71.137 (4.68.71.137) 3.245 ms 2.877 ms 2.889 ms 5 * * * 6 ae-28.r00.lsanca07.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.9.93) 3.731 ms 3.483 ms 3.850 ms 7 ae-3.r01.lsanca07.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.5.29) 3.517 ms 3.433 ms 3.458 ms 8 ge-101-0-0-3.r06.asbnva02.us.bb.gin.ntt.net<http://us.bb.gin.ntt.net> (129.250.196.153) 69.503 ms 68.021 ms 68.072 ms 9 ge-101-0-0-3.r06.asbnva02.us.ce.gin.ntt.net<http://us.ce.gin.ntt.net> (129.250.196.154) 67.075 ms 67.102 ms 67.122 ms 10 * * * 11 * * * I recall ARIN had a DDoS attack a week or so ago.
