HI all I wonder if anyone here has had complains from their customers/helpdesk regarding inability to access certain chinese websites. For example the last 5 hops of a trace to www.china.com shows it disappearing after 201.176.155.238 15 hkt.ser4-0.core1.sun.cais.net (63.216.17.73) 245.372 ms 240.922 ms 237.96 0 ms 16 202.84.249.29 (202.84.249.29) 236.565 ms 235.41 ms 234.18 ms 17 207.176.97.134 (207.176.97.134) 245.263 ms 235.18 ms 238.485 ms 18 f5-1.tmh12.hkt.net (205.252.128.238) 245.80 ms 239.694 ms 243.223 ms 19 210.176.155.238 (210.176.155.238) 244.516 ms 246.827 ms 235.416 ms 20 * * * There's also been problems with some other sites ( can't remember names but perhaps one of them is cn.yahoo.com) Any ideas? regards Lin --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
Lin, that's probably not quite what it looks like. The Web site loads OK, and you can ping it, but you can't traceroute to it with UDP, only ICMP ECHOs. -- Juha :: -----Original Message----- :: From: owner-nznog(a)list.waikato.ac.nz :: [mailto:owner-nznog(a)list.waikato.ac.nz] On Behalf Of Lin Nah :: Sent: Thursday, 19 July 2001 17:18 :: To: nznog(a)list.waikato.ac.nz :: Subject: Problems accessing sites in china :: :: :: HI all :: :: I wonder if anyone here has had complains from their :: customers/helpdesk :: regarding inability to access certain chinese websites. :: :: For example the last 5 hops of a trace to www.china.com shows it :: disappearing after 201.176.155.238 :: :: 15 hkt.ser4-0.core1.sun.cais.net (63.216.17.73) 245.372 ms :: 240.922 ms 237.96 :: 0 ms :: 16 202.84.249.29 (202.84.249.29) 236.565 ms 235.41 ms 234.18 ms :: 17 207.176.97.134 (207.176.97.134) 245.263 ms 235.18 ms :: 238.485 ms :: 18 f5-1.tmh12.hkt.net (205.252.128.238) 245.80 ms 239.694 :: ms 243.223 ms :: 19 210.176.155.238 (210.176.155.238) 244.516 ms 246.827 :: ms 235.416 ms :: 20 * * * :: :: There's also been problems with some other sites ( can't :: remember names :: but perhaps one of them is cn.yahoo.com) :: :: Any ideas? :: :: regards :: Lin :: :: --------- :: To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz :: where the body of your message reads: :: unsubscribe nznog :: :: --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
