+**Our stability guarantees**: many of our services rely on publicly-accessible storage and APIs, but not all of these are intended for public consumption. At the moment, **only the resources behind `static.rust-lang.org` are considered stable**, meaning that those resources will not change without (at least) prior notice. If you are relying on other parts of the Rust project infrastructure for your own work, please let the infrastructure team know.
