I know this comes up occasionally, but here it is again. I'm experiencing pretty bad loss through CRL to both wcarchive and freefall. Interestingly, the paths are different, implying that either CRL or MCI is confused. The path to freefall is: 3 paloalto-cr7.bbnplanet.net (131.119.26.41) 30.734 ms 29.428 ms 27.347 ms 4 paloalto-mci.bbnplanet.net (131.119.0.202) 32.157 ms 30.227 ms 29.911 ms 5 bordercore4-hssi0-0.SanFrancisco.mci.net (166.48.19.249) 39.666 ms 33.467 ms 31.616 ms 6 mae-east-nap.Washington.mci.net (204.70.1.214) 109.955 ms 118.960 ms 115.936 ms 7 mae-east-nap.Washington.mci.net (204.70.1.214) 113.201 ms 109.630 ms 107.709 ms 8 mae-e-1.e0.crl.com (192.41.177.104) 115.320 ms 117.094 ms 112.848 ms 9 gateway-sfo1.atm.us.crl.net (165.113.56.30) 818.783 ms * * 10 * E0-CRL-SFO-02-E0X0.US.CRL.NET (165.113.55.2) 693.770 ms * 11 T1-CDROM-00-EX.US.CRL.NET (165.113.118.2) 781.045 ms * * 12 freefall.FreeBSD.ORG (204.216.27.18) 812.247 ms 767.955 ms 736.962 ms Weird that it goes via mae-east. Interesting that it takes MCI ~80ms to get cross-country, and it takes CRL ~700ms (and lots of lost packets). --- freefall.freebsd.org ping statistics --- 42 packets transmitted, 14 packets received, 66% packet loss round-trip min/avg/max = 630.338/709.732/767.077 ms and 3 paloalto-cr7.bbnplanet.net (131.119.26.41) 29.500 ms 28.991 ms 27.637 ms 4 paloalto-mci.bbnplanet.net (131.119.0.202) 30.061 ms 30.525 ms 29.762 ms 5 bordercore4-hssi0-0.SanFrancisco.mci.net (166.48.19.249) 33.196 ms 30.608 ms 30.256 ms 6 mae-west-nap.SanFrancisco.mci.net (204.70.1.14) 74.390 ms 69.798 ms 64.949 ms 7 mae-west-nap.SanFrancisco.mci.net (204.70.1.14) 64.856 ms 65.071 ms 68.148 ms 8 * T3-CRL-SFO-01-H1/0.US.CRL.NET (198.32.136.10) 71.430 ms * 9 T3-CRL-SFO-01-H3/0.US.CRL.NET (149.20.64.19) 109.910 ms 115.390 ms 113.418 ms 10 wcarchive.cdrom.com (165.113.58.253) 116.339 ms 153.449 ms 165.374 ms A small but noticable jump in RTT's between the two CRL hops, and of course more lost packets. --- wcarchive.cdrom.com ping statistics --- 49 packets transmitted, 38 packets received, 22% packet loss round-trip min/avg/max = 78.840/185.960/267.531 ms Pretty high RTT variance there. Now, despite the network problems, I note that wcarchive is hitting its limit of 1200, so there must be *some* people getting through... (Or, maybe people keep hitting it in parallel because the performance is so bad...) Bill
