I remember seeing a startup at one point that wanted to put mini-CDNs in people’s homes. Small black boxes that would automatically be a CDN not just for your home, but the whole area. Of course, sites would have to use their CDN network, etc.

I actually thought it was a really interesting idea. Almost like federated CDNs.

Imagine if every Xfinity router has a built-in 16TB CDN: it would be an interesting way to possibly change how bandwidth works and makes it back to the DCs. Most popular stuff would be closer, faster.
