Thank you very much, an experimental `wget` shows I get much higher speeds from this: ``` $ wget https://mirror.sjtu.edu.cn/guix/nar/lzip/1bdldr80p39g1mjnh76xw6hmwqrrb8lz-wine64-6.0 --2021-03-06 06:45:10-- https://mirror.sjtu.edu.cn/guix/nar/lzip/1bdldr80p39g1mjnh76xw6hmwqrrb8lz-wine64-6.0 Resolving mirror.sjtu.edu.cn (mirror.sjtu.edu.cn)... 111.186.58.212, 2001:da8:8000:7100::322:a Connecting to mirror.sjtu.edu.cn (mirror.sjtu.edu.cn)|111.186.58.212|:443... connected.

Would it not be appropriate to somehow put a list of such substitute servers (even if it is currently only a single mirror) somewhere official, like the Guix manual? I suppose if Peng Mei Yu thinks this mirror would be maintained long term? Thanks raid5atemyhomework
