I'm gonna go out on a limb here and say that the older snapshots have been removed from server.

@graydon should this be closed?

[ivan]

I was interested in grabbing all of these in case I later went through the work of re-bootstrapping Rust from scratch, to make sure no compiler worms slipped into that 50MB of machine code. I guess this could probably be done without the official snapshots.

[graydon]

Oh, I probably missed one when moving them from dl.rust-lang.org to static.rust-lang.org

[ivan]

I think a lot more than one is missing; when I checked about a month ago, (almost?) everything older than that one 404ed as well.

[catamorphism]

Nominating -- I think we should decide whether it's important to preserve the entire snapshot history.

[catamorphism]

We decided this is a theoretical concern and that we can't realistically keep the entire snapshot history around; it also wouldn't be realistic for someone to do the bootstrapping exercise from scratch. That said, leaving it open to remind us that the history is incomplete.

Triage bump. I think this bug could be closed after documenting it in https://github.com/mozilla/rust/wiki/Note-compiler-snapshots

[frewsxcv]

For what it's worth, the original link @ivan (the OP) posted works for me and I'm able to download that snapshot. I think this can be closed?

[flaper87]

Closing as per previous comments.
