domain name

do I take advantage of this to change domaine name:


  • could test more easy
  • could redirect old domain name to new one untile end of gandi domain (2026)
  • get a more "normal" extention


  • need to progresively update every personal account

Container localisation

on hetzner:

  • need to increase memory

on homelab:

  • need to redirect all serveur flux to hetzner to be sure to be sure that mail will be send with hetzner IP (control PTR on this IP)
  • hetzner will be too a SPOF

software choose
