Ah, good to know. I assumed the index was hosted as part of crates.io but I didn't actually bother to check. The point I was trying to make (even if I didn't communicate it properly) was that if crates.io goes away for good, the index will too and so it won't really matter that the code is inaccessible because cargo won't know where to find it anyway. Of course, based on what you said, it's certainly possible for everyone involved in crates.io to get hit by a bus and crates.io vanish when the S3 bill goes unpaid while still leaving the index up on GitHub, but if crates.io is taken down intentionally then presumably so will the index.
