据我所知，亚马逊正在阻止 ICMP (ping) 请求。如果您想执行某种“is it up”请求，您可能需要实现一些其他例程，例如基于 Web 的“ping”页面；只要让它显示你击中它的时间即可。
As far as I am aware, Amazon is blocking ICMP (ping) requests. If you want to perform some sort of "is it up" request you may want to implement some other routine like a web based "ping" page; just have it display the time when you hit it.
