My concern is what happens when popular-library.io goes down or gets hacked?

Or how about attack vectors like DNS poisoning? or government-based firewalls?

I know there's this[1], but somehow I still feel uneasy because the web is so fragile and ephemeral...

At the very least I would like to have the standard library offline...
