Thanks again for setting this up! The us-east mirror makes a big difference for me. The wget output is below, but anecdotally, last week, when I installed Guix on a new Debian installation, my first `guix pull` failed maybe three times due to substitute timeouts before I enabled the mirror. After enabling the mirror, it succeed on the first attempt. Tangentially, a few months ago I was using a very poorly connected network that had the additional annoying property of disconnecting every 10 minutes or so. I got stuck downloading the beginning of one large nar enough times that eventually I gave up. I found, though, that `wget -c` was able to complete the download (though it took several attempts). Adding some similar resume functionality might at least help to mitigate the impact of slow downloads. > > France: wget > https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > US: wget > https://bordeaux-us-east-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > Singapore: wget > https://bordeaux-singapore-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > > > So please share the output from wget and if you're comfortable doing so, > the rough real world location of where the computer doing the > downloading is. > Here are results from Florida, US: philip@avalon:/tmp$ wget https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 --2023-05-25 16:27:53-- 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.
