cdn-动态加速导致节点疯狂访问test.html的疑问

最近一段时间在测试各大CDN服务商的线路性能,有朋友告诉我阿里云的全站加速,也就是他们自称的dcdn性能不错,让我有时间可以测试一下他们的性能,我在昨天晚上登录阿里云的全站加速配置页面,配置了一个网站,试了下,速度确实不错,特别对图片的加速那是刚刚的。

对我了解的朋友,可能都知道我这人喜欢查看日志,我通过tailf命令查看日志发现有点不对,日志中产生了大量的404访问记录,全是访问一个根目录下面没有的文件test.html,难道是让刷流量了,我查了下IP,竟然全是阿里云的加速节点IP,难道业内传的说阿里云刷客户流量的事是真的,真是让人吓了一大跳,我立马把域名从阿里云的加速面板中删除,大概过了十几分钟,这种现像没有了。

这些IP通过阿里云提供的工具查询可以认定百分百是阿里CDN的节点IP,这么大的一个公司难道真的会刷流量,让客户的流量用的多些,他们赚的钱更多吗,想想不太可能,于是想到提交工单问下到底是怎么会事,以下是他们的工单回复

工程师 69576 号 : 您好
这个是cdn的正常的测试端口是否正常的请求。这些请求主要是动态加速CDN用来对源站做健康检查使用的,用来做回源链路探测和源站状态探测的。
建议您的web需要对于test请求不要动态处理,直接web做静态处理就可以了。
同时您看看您的站点是否必须使用动态加速,如果不使用的话,可以控制台关闭动态加速。就没这个请求了,请您了解,谢谢

通过他们回复的工单我们知道,这些疯狂访问根目录下面test.html文件的事情的确是他们的节点搞出来的,这样搞的目的竟然是动态加速时CDN节点对于源站的健康度检查用的,如果不用动态加速就不会出现这种现像。

测试继续,我又把域名重新添加进全站加速DCDN控制面板,该死的节点又开始疯狂的访问这个根本不存在的文件了,于是我立马上登录面板如上图所示把动态加速的开关给关了,十几分钟后,这种现像果然没有了,真是服了阿里了,用这种方法检测源站的健康度,怪不得网上一直有人流传着说阿里刷用户的网站流量呢。

如果能有阿里的技术高层看到我这篇文章,希望把这点改进一下,这样搞会把客户吓跑的。
