冷知识：互联网能否被人为关闭
互联网
互联网对于现在人而言已经成为我们生活、工作中必不可少的沟通方式，如果有人妄想关闭它，能否做到呢？
黑客
早在2007年2月，当时最大的网络攻击试图端掉13个根域名服务器，要知道，那里可是承载着全球正在使用的所有网络地址，是网络流畅运行的必需数据。结果，只有2台美国服务器受到了影响，还有11台毫发无损，这就代表攻击因此失败。
因为网络大部分基础设施，包括服务器、电缆和卫星，以及负责运行的网络运营商等，都掌控在私人手中。一个政府或许可以命令其版图内的网络运营商关闭，但是，人们还是可以通过不归政府管辖的公司的卫星连接获取数据。要跨越国界去关闭网络，几乎是不可想象的。
所以任何人也无法关闭掉互联网
