It feels faster downloading from those locations.

I performed the following tests using the same machine where downloads 
where faster last time, but changed two things:

+ Upgraded Guix System to 849286b (May 26, 2023)
+ Moved closer to the WiFi access point (1 m away)

Before starting the tests, I checked the average download speed at the time:

Connection: WiFi
Promoted service speed: 60 Mbps
Reported download speed: 48.8 Mbps
