Dear all,

I am trying guix import from cran, and building some R packages, which
sometimes needs to download substitutes. i noticed that the download
speed can be ridiculously slow and seems especially during night in
HKT.

Here is a snippet of the downloading:

One of ghc-* (not shown above) which weights around 97MB took 2 hours
to download.
But when I use speedtest.net to test my internet speed
(https://www.speedtest.net/result/9675438421) I get about 80Mbps both
upload and download, while some substitutes are still download (and
they are still downloading when I am typing this).

So is this problem with my guix setting or is it known that
ci.guix.gnu.org is slow?
This guix is installed on Linux Mint 19.2, and I did "guix pull" yesterday.

Regards,
Peter
