static - 问一个关于 javascript 加载的问题

Question

用chrome浏览器访问segmentfault，几乎所有javascript都失效，查看加载信息，如下所示：

Script from origin 'https://dfnjy7g2qaazm.cloudfront.net' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://segmentfault.com' is therefore not allowed access.

调查了一下（非义务，纯好奇），似乎把静态文件放在AWS上要做些设置：

或者在Nginx服务器加配置：

location ~* \.(eot|ttf|woff)$ {
   add_header Access-Control-Allow-Origin '*';
}

或者在AWS上配置:

大家说哪种办法好呢？

经研究，翻墙访问 sf 可复现这个现象，但是我换了一个日本的节点访问，却不跨域了，然后再切回原来的翻墙节点 hk，也不再出现跨域问题，总之很诡异。
