Running a simple hf download Qwen/Qwen3-4B in colab, I keep getting infinite retries with: WARN Status Code: 500 With RuntimeError: Data processing error: CAS service error : Reqwest Error: HTTP status server error (500 Internal Server Error), domain: ``https://cas-server.xethub.hf.co/reconstruct…

I solved the issue by disabling xet, like this: export HF_HUB_DISABLE_XET=1 After setting this environment variable, the download worked perfectly. :blush:

WARN Status Code: 500

Other Hub features also appear to be unstable due to the AWS outage.
