Today's internet is by land, sea, air and space

The internet is an invisible mesh that enables instantaneous global communications, but delivering all those bits quickly to more people in more places requires increasingly exotic approaches. Here are a few things you may not realize about how communication pipes work around the world:

1. Hundreds of thousands of international cables are actually buried underwater. 
2. Even the cloud is increasingly moving under water.
3. "Wireless" technologies actually use a ton of wires. 
4. Those wireless base stations often stick out like a sore thumb. That's why wireless towers are often disguised to look like other things. 
5. Space has become the new frontier for wireless signals.
