Just opened an office in Nanjing, China and we have 2 lines in - one 2 MB line with fixed IP and one 10 MB line with variable IP address. Pinging the local IP (China Telecom) is great (1 ms), going inside China is ok usually to very slow sometimes, but going to the US is terrible to not at all. Anyone have any hints about setting up a good line back to the states? |

| Yes. I'm not sure that we have any options. We have China Telecom coming over, but they are a government owned monopoly and I'm not sure how much they will dig.
From things like a tracert it looks like some of the problem is in China but some is AT&T in the US. How do you get a better route to a part of the US. It seems that we get better results in the Western US than the East.
Do you have any experience in China?
Thanks much. |

Last time being there was 3 years ago? Many probably has changed since then.
I will suggest you to use VPN via a server outside of China to a server preferably in US East Coast, but then again if the connection sucks that will probably not help.
Wait until the China Telecom technicians comes and see what they can do first then.

china | Hey asellus - China Telecom can not do anything since the problems seem to be all along the route. Another local company suggested using MPLS. They say that they are getting 60 ms access at 4 MB back to the states. Maybe. |

MPLS is expensive though.
Can you paste the forward traceroute to a US site and reverse from the US site back to you?
There is a line quality tester on this site you can try out if not. As per the instruction, put in your public IP address (if not detected). Let the test run, you should see 2 traceroutes from 2 sites in US back to you. Then from your system, traceroute back to these 2 sites (hop 0).
Paste the results here or link it if you can and let us see what you're getting.

Looks like you have quite heavy packet loss in the last few hops, not to mention the relatively high latency that you're getting.
Appears to be ISP issue, looks like you need to change your route by using proxy server or VPN.
All the best! |

Not in Nanjing but same issue in Shanghai. Has anyone had any sucess in getting the isp (CHINA TELECOM) to route through a different gateway? I have tracerouted three networks and all three networks route through a different gateway. They just don't seem to share the information between each other.
Also does anyone know what number to call as well?????? because that seems to be one of the hardest thing to get a hold of.
