A new Rust blog post/announcement has been posted!

Like the rest of the Rust community, crates.io has been growing rapidly, with download and package counts increasing 2-3x year-on-year.

If the API is down or slow, it affects all download requests too. In fact, the number one cause of waking up our crates.io on-call team is "slow downloads" due to the API having performance issues.
