RE: [OT] Dalian ISPs?

Jim,

Interconnection between ChinaNet and Sprintlink is always clogged. This week
it has been at its worst for this year yet. I am also clocking the same as
Adam. If you buy a broadband service from a locally competing carrier, e.g.
Unicom, be advissed that Unicom's network peers with ChinaNet which is the
lifeline to anyone wanting to access content outside of China. Whatever you
do you will go through a CNC or a China Telecom Network. (Bad) Service
Guaranteed!

You can get more information on China's networks from www.cnnic.net (they
have network diagrams and bandwidth breakdowns),
http://www.citynetchina.net/english/GreatExpectations031029.pdf. Lease a
line and a 10 meg port on the interlink between China and the US. Might set
you back a couple 100 K though.

I'm getting 400-500ms to mit.edu on DSL in Beijing. Traceroute is better
than yours, but it's the same problem. Here's an excerpt:

  7  202.96.12.37 (202.96.12.37)  7.449 ms  7.237 ms  7.186 ms
  8  219.158.3.14 (219.158.3.14)  7.516 ms  7.054 ms  7.126 ms
  9  sl-gw23-ana-1-0.sprintlink.net (144.228.173.249)  491.745 ms
487.764 ms  493.701 ms
10  sl-bb20-ana-3-3.sprintlink.net (144.232.1.45)  496.404 ms *  458.940 ms
11  sl-bb24-ana-13-0.sprintlink.net (144.232.1.138)  495.507 ms  463.220
ms  484.884 ms

That jump to sprintlink is the big one, and it's happening at the same
time as yours. I haven't been following the discussion too closely, but
it looks like the biggest problem might not be in Dalian. That 60-70ms
ping before the jump to sprintlink is suspect, though.
