.com 根服务器直接部署在了广州墙内了吗? 好像都不过墙了,这延迟 GFW 要抢答都没机会了,多个省份似乎也走到广州

有什麼影響嗎?

虽然但是,你的结论是错误的。你不会以为现在的防火墙还只部署在“海关”出口吧,早就边缘化了。

他再怎么快难道不走运营商线路?
用户 --> 电信运营商 --> 权威 dns 1 ,com,net 根在国内有 Anycast 节点,由 VeriSign 维护( a-m.gtld-servers.net ) 2 ,中国有在境内建设 root 镜像根,上游是 13 个根服务器中的一个,镜像由中方维护( a-m.root-servers.net ) com,net 的境内节点完工日期甚至早于很多 |

@jiuhuicinv 早于很多镜像根,但它们本质没有什么关联

@gentrydeng #1 说的是根,.com 也是类似的。话说回来运营商的 DNS 污染也不是靠墙做的。

没啥意义,你向谷歌的权威 DNS 请求 youtube.com 的 A/AAAA 记录的时候照样有抢答
