When error 429 occurs, it [may be caused by IPv6](https://discuss.huggingface.co/t/how-does-the-hub-handles-http-error-429/147346/3), [an outdated implementation of the old datasets library](https://github.com/huggingface/datasets/issues/7344#issuecomment-2582422510), or [other factors](https://github.com/huggingface/datasets/issues/7506).

If it is truly an intentional rate limit, I believe only Hugging Face can resolve it…
