The internet isn’t a series of tubes, it’s a series of wires. And many of those wires are underwater. The animals know this, and are trying to exploit our weakness.
Apparently, sharks like to eat fiber cables that we use to share cat videos with the world. They either just like to bite things they find, or they enjoy the taste of them. Either way, they are intentionally going after our communications networks, which means a large-scale attack may be imminent. The problem is so bad that Google is now wrapping its cables in Kevlar.
The battle rages on.
