Summary
A programmer used the caches of 3.9 million open DNS resolvers to store file fragments, creating an absurd open-source project called dnsfs. The files disappear as the caches expire.

A programmer had a wild idea:
DNS resolvers cache domain names for days——
What if you could store files in them?
↓
He found 3.9 million open DNS resolvers across the entire internet
Chopped the file into pieces
Scattered them across the web
No hard drive, no database, no cloud
The file lives in the caches of countless servers — servers that have no idea they’re storing anything
What if nobody visits it?
The file slowly “dies” as servers one by one forget it
This is one of the most absurd open source projects I’ve ever seen
It’s called dnsfs
What file would you store in a DNS cache?
