互联网其实在海底
Almost all international internet traffic travels along cables lying on the sea floor, which break regularly and are repaired by ships.

互联网其实生活在海底。把这个故事分享给还在说“一切都在云端”的人。几乎所有跨越海洋的信息都不会飞到任何地方,而是沿着铺在海床上的电缆传送,穿过寒冷黑暗的深海,与鱼和螃蟹为伴。
这些电缆比人们想象的要细得多。在几乎没有什么能触及的深海远处,有些电缆的粗细和一条花园浇水管差不多。内部是细如发丝的玻璃纤维,光沿着这些玻璃传送,承载着照片、通话、电影,以及你发往另一个大陆的每一句话。
有些东西会把电缆弄断。并不是鲨鱼,虽然确实有一次鲨鱼咬过电缆,这个故事至今流传不衰。真正的元凶大多是渔具和拖在海床上的沉重船锚。这种事每年在世界各地发生一百多次。之后,一艘船会出海,找到断裂的电缆,把它从海底拉起,把玻璃纤维重新接好,再放回海里。原来,所谓的“云端”也会晕船。
That's the story.
