Re: Test US mirror for bordeaux.guix.gnu.org and slow downloading of substitutes

[Blake Shaw <blake@sweatshoppe.org>]

Hi Christopher,

So its strange, I do:

wget https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0
--2022-05-25 05:32:12--
https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0
Resolving bordeaux.guix.gnu.org (bordeaux.guix.gnu.org)...
185.233.100.56, 2a0c:e300::58
Connecting to bordeaux.guix.gnu.org
(bordeaux.guix.gnu.org)|185.233.100.56|:443... connected.

...and then it just remains stalled there. wget appears to work fine
in generat though, just not with guix.

Any idea why this might be happening? Could bordeaux be blocking IPs
in Singapore?

Best,
Blake
