Weird that only some worksites don't work.. it's a bit how a friend living over in China describes it - randomly some stuff is blocked. I hope we are not there yet..
Yes, well, I had an issue with getting to the Billion website in AU ... the ISP claimed no block, Billion claimed no block -- I got a temporary extra block of IPs to test and another IP was fine from the same ISP, but they never did find out what was blocking my normal IP, not the ISP, nor Billion. In the end I just routed the connection via another service, but most people don't have multiple services to /choose/ from.
True. At the moment I have two links but one should be decommissioned soon. Interesting the difference between traceroute when using ICMP and TCP port 80: $ traceroute -I www.zeit.de traceroute to www.zeit.de (217.13.68.220), 64 hops max, 72 byte packets 1 115.186.196.105 (115.186.196.105) 20.636 ms 20.494 ms 20.224 ms 2 3812.Gi0.br1.cit190.uecomm.net.au (218.185.31.142) 19.917 ms 20.789 ms 20.960 ms 3 VLAN323.o3mlc76f05.optus.net.au (61.88.143.197) 20.641 ms 22.014 ms 21.419 ms 4 203.208.192.241 (203.208.192.241) 195.414 ms 194.884 ms 195.379 ms 5 203.208.172.242 (203.208.172.242) 194.133 ms 203.208.172.238 (203.208.172.238) 194.407 ms 203.208.172.246 (203.208.172.246) 194.606 ms 6 80.150.171.41 (80.150.171.41) 196.557 ms 197.589 ms 196.317 ms 7 bs-ea1-i.BS.DE.NET.DTAG.DE (62.154.99.34) 357.788 ms 358.499 ms 364.120 ms 8 dtag.gaertner.de (80.150.168.230) 353.579 ms 354.360 ms 354.330 ms 9 www.zeit.de (217.13.68.220) 355.478 ms 355.685 ms 358.413 ms BTW: I can ping www.zeit.de on both without packet loss..

I don't understand it.. Why do the port 80 packets loop forever? I never worked for an ISP so maybe people with this background have seen this before? I also see that the old link is using US addresses, the new one Singapore.. Regards Peter
