There's similar topic at
https://bitcointalk.org/index.php?topic=5169284.0 which should answer some of your question (even though it should be "Bitcoin source code" rather than "Bitcoin").
- are backups performed periodically? what / when / by whom
- are these backups held publicly (where) or only privately (by whom)
At very least, all bitcoin contributor/developer automatically make private backup when they run command such as
git clone or
git pull- what is the emergency assembly point (is btctalk/chan/bitmessage appropriate)
Probably IRC or public mailing which often used by Bitcoin Core developer/contributor
Thanks for sharing this interesting link... I skimmed it, and sadly seems that nothing really substantial was done to alleviate this impending threat... funny how some proposed to use vpn to bypass this previous censorship... but totally useless.
Fundamentally it's not the code source which is at risk, it's way to decentralized. It's more what's all around it with github... that's what needs to decentralized ASAP ! that should be a crypto wide effort, to have at least 2-3 "decentralized github".
