[CC'ing Chris as bordeaux expert] I'm affected by this issue as well. On both my desktop machines with Guix System installed for quite a while (so not in the installer).
It also happens at different ISPs: * Telefonica O2 DSL, Germany * NetCom BW (ASN 47297) On one machine I removed the bordeaux server from the substitutes servers as this is super annoying. On the other I'm in the proccess of removing it... ~Jonathan
