Upload speeds extremely slow / stalling since April 1st

Since yesterday afternoon (April 1st), I’ve been experiencing extremely slow upload speeds when uploading GGUF model files to the Hub using hf upload. The uploads start at a reasonable speed but progressively slow down from ~1 MB/s, then downgrades to a few KB/s, and eventually stall completely at ~110 KB/s with seemingly no progress at all.

What I’ve tried:

• Uploading all files at once vs single file, same issue
• Disabling xet (HF_HUB_ENABLE_XET=0) and hf-transfer (HF_HUB_ENABLE_HF_TRANSFER=0), same issue
• Using an older version of huggingface-hub (0.36.2) — same issue
• Checked status.huggingface.co, no reported issues
• My internet connection is fine for everything else

The pattern is consistent: uploads begin at normal speed, then gradually degrade over a few minutes until they completely stop progressing. This happens regardless of file size or number of files being uploaded.

Environment:

• huggingface-hub: 1.8.0 (also tested with 0.36.2)
• OS: Windows 11 Pro
• Files: GGUF model files ranging from 11GB to 47GB

This was working fine until yesterday. Is anyone else experiencing similar issues?
