A user on the Hugging Face forums reports experiencing severe network instability and bandwidth throttling when downloading large GGUF files (over 20GB) from the Hugging Face CDN. The issue is isolated to users on the Telmex ISP in Mazatlan, Sinaloa, Mexico, where connections exhibit a "sawtooth" behavior with speeds dropping to 0 MB/s.
- Location: Mazatlan, Sinaloa, Mexico.
- ISP: Telmex (Fiber Optic, 250 Mbps plan).
- Ping to huggingface.co is stable at 22ms with 0% packet loss.
- Cross-provider tests show GitHub CDN (Fastly) runs at a flat 300 Mbps without drops, isolating the bottleneck to the Hugging Face/Cloudflare routing path for Telmex users.
The user requests that the infrastructure team review the routing matrix or CDN peering agreements for Telmex MX to resolve the issue.
