最近使用阿里的公共 dns， QQ 空间一直打不开，到底谁掉了节操？

[chromie]

是阿里还是鹅厂？

[MSDOS]

或许是 ISP ？现在的 ISP 都不喜欢用户用别家的 DNS 。。。。。

[zro]

楼主什么 ISP ？ QQ 应该还有点节操的

[FFLY]

个人认为鹅厂的 DNS 是国内目前最好的 DNS ，阿里的那个貌似已经放弃更新了。

我猜是阿里，最近用各种问题

[learnshare]

我最近用阿里的 DNS 天猫都解析到台湾去了，你说节操属于谁

[heww]

我会说有段时间手机上用 uc 浏览器打不开 3g.163.com 然后换个浏览器就打得开。

[chromie]

@zro 中国电信

[jeeve]

呵呵，你可以试一下 paypal 是不是也打不开？ 阿里 DNS 呵呵....

[Bryan0Z]

@heww 解析到台湾算什么，看 B 站解析到内网（ 127.8.0.1 ）才叫厉害……

[zro]

换 DNS 吧， 119.29.29.29 应该不错，如果电信不劫持 53 端口的话

[Delbert]

我在学校用阿里 DNS ，连学校首页都很难打开……

什么情况？

[wangluowangwang]

@heww UC 是这样子的，在 WIFI 下很多网站打不开……

[zro]

@wangluowangwang 原来也解析不出来啊？感觉国内 DNS 这几个月怪怪的，难道是墙升级引起的？

[kiah]

还是用 114 吧。。

[FFLY]

@wangluowangwang 你是有多蛋疼，用国内的 DNS 解析被墙的网站。
