The following URL downloads at about 50 KB/s from Cape Town:
https://conda.anaconda.org/nvidia/linux-64/libcurand-dev-10.3.0.86-0.tar.bz2
I’ve tested this from inside AWS Cape Town Datacenter, and from my home close to Cape Town, and both exhibit the slow download speed.
However, when downloading from a US datacenter, I get full speed.
This looks to me like a Cloudflare issue.
