-## Rate limiting on managed public buckets through `r2.dev`
-
-Managed public bucket access through an `r2.dev` subdomain is not intended for production usage and has a rate limit applied to it. If you exceed the rate limit, requests through your `r2.dev` subdomain will be temporarily throttled and you will receive a `429 Too Many Requests` response. For production use cases, consider linking a [custom domain](/r2/buckets/public-buckets/#custom-domains) to your bucket.

 Limits specified in MiB (mebibyte), GiB (gibibyte), or TiB (tebibyte) are storage units of measurement based on base-2. 1 GiB (gibibyte) is equivalent to 2<sup>30</sup> bytes (or 1024<sup>3</sup> bytes). This is distinct from 1 GB (gigabyte), which is 10<sup>9</sup> bytes (or 1000<sup>3</sup> bytes).
