有时候 Firefox 打不开 Bing ，报错。是谁的错？

近几年来有时候会发生 Firefox 打不开 Bing ，网页显示：

Access Denied

You don't have permission to access "http://cn.bing.com/" on this server.
Reference #18.922d3e17.1710414717.20f611cc

Access Denied

Access Denied

Reference #18.922d3e17.1710414799.20f9a534

这样的错误。
而这时候用其它浏览器，如 Edge, Vivaldi, Iron, Waterfox 等都可以打开。

这是 Bing 的错还是 Firefox 的错？
有时候过一会儿就好了，什么也没做。

今天访问 http://rhn.redhat.com 也遇到相同的现象，而且是所有浏览器都是如此

看来这是网站的某种保护机制，可能不知什么原因触发了 Bing 的这种保护机制。

viewtheard：没遇到过,检查下win区域回到原帖

Windows 设置的区域是 +8 区，不过这个应该无关，因为不管你 Windows 设置的是什么时区，Bing 是根据你的 IP 地址所在地是中国大陆来强行把你转向到 cn.bing.com 的。
