Re: China internet issues

[Vinod Ola]

Basically we using Zscaler proxy and through that outlook latency is so high and disconnections to outlook specific. Without Zscaler proxy we are good. Not sure how to get complete path where it can show latency.Sent from my iPhoneOn 22 May 2024, at 11:33 PM, Brandon Zhi  wrote:One of the issues in China is the existence of the Great Firewall. Its impact is not only about blocking access, but also throttling non-mainland traffic during peak hours, such as in the evenings, through QoS restrictions.Additionally, similar to most Asian home ISPs, Chinese ISPs are not inclined to optimize international routing. Usually, all non-mainland traffic is routed through the United States or European countries instead of connecting directly. Even for traffic to Hong Kong, if there is no paid peering agreement, the traffic from China Telecom's home broadband users will be routed through the United States before reaching Hong Kong.Basically means you have to pay the 3 largest ISPs in China to have a better performance for users in China Mainland.Brandon ZhiHUIZE LTDwww.huize.asia | www.ixp.su | TwitterThis e-mail and any attachments or any reproduction of this e-mail in whatever manner are confidential and for the use of the addressee(s) only.

The three major ISPs are
China Telecom, China Unicom, and China Mobile. However, most issues
are probably related to the Great Firewall (GFW). It can do many
different things (DNS poisoning, IP blackhole, IP:port block, TCP
reset, etc.) on the state level.
