Which DNS service is friendly to China?

I have tried the free nameservers by Rackspace, Vultr, Cloudflare, they all got bad results in China. I know this is influenced by GFW maybe. Do you know which DNS service is friendly to China location? Thanks.

    There are many free DNS services in China!

    https://www.dnspod.cn/ - > Very common --> English: https://www.dnspod.com

    https://www.dns.la/

    I think the usual problem is congestion at China Telecom or Unicom's backbone. Therefore, you need to find an ISP with direct peering to CN. (e.g. PCCW)

    How about dns servers inside China? Like alidns. Unless if you are targeting worldwide users that is.

    The problem is that the GFW is very advanced by now - You can buy filtering HW from Huawei that does 100G DPI in ASICs by now for way less than a 10G Cisco FW, as a de-facto government "influenced" enterprise (come on, the owner/CEO was Major in the PLAs IT dpt, his ex-wife the daughter of a province governor, he was in national "congress" and Beijing tells this company is independent? Yea... ) the gov probably has access to more sophisticated designs based on this.

    Likely the DNS servers are not even blocked, the GFW just replaces the result on-the-fly with a Chinese IP, NXDOMAIN or 0.0.0.0.
