目前还在和客服对话沟通中，效率有点低

也太敷衍了

问题是正常的国内机子，怎么会访问不了Cloudflare

@xuefengjia1 #3 没装这个

搞了半天，阿里这样回复

您好，看您的服务器是大陆地域的，而您访问的cloudflare.com 的是海外网站，大陆访问海外会存在跨境链路的情况，导致访问不稳定，如果您那边主要是希望访问海外站点的网站，可以考虑使用海外地域的服务器去访问

我也有过这样经历，阿里云说是运营商提供的IP阻断了海外的网站访问。他一直跟我扯是上游供应的问题，ip也不给我换，他也无能为力。我非说他们提供的产品有质量问题，让他自己跟上游沟通，反正我买到你的产品是有问题的（没理由我去水果店买到烂瓜，要我自己去联系果农理赔吧）。我说开发的需求是要访问一个部署在海外的网站例如（https://ifconfig.me/），然后他服软了，给我退款，退全额新人优惠券，让我重新买新机，新机ip正常

我就是探针走cloudflare获取ip而已，算了改探针
