Dealing with China firewall


I need some advice if I should keep on my little NTP server or just quit,

I joined NTP pool to volunteer my 20Mbits/s upload in Taiwan for years,
follow by setup recommendations, using NTPD and recommended configuration.

just recently discover I am not able to access part of China website for some reason,

as my ip address is kind of static by request, I can change it if I want,
so I do a few test around this,

once I changed my ip, I can access those china website for few days,
then I am blocked again.

I have ruled out most of my home server service which could have any complicate with network traffic to China,
as now I have around 10k pps request flood from China to my home server for NTP request,

my guess is China firewall intentional block my ip due to tremendous UDP traffic on chart.

any advise?


Your server is in the tw or the cn zone? Sounds like we need (a lot) more servers in tw, too…

I’m pretty sure I know how to put together the features to “rebalance”, just need the time to type out the code (and test, etc etc …)


in tw, but 90% of the NTP tracffic coming from China.


here is a website that I can’t access once I got flag on Great Firewall

once I score 10 and start serving NTP, I no longer able to access this site,
then I need to change my ip address if I wanna access any similar site locate in china.
