When using multiple Artica servers and also Debian systems, it is very interesting to build a local repository mirror on your local network, delegate an edge server for this job and configure the internal clients to fetch software from its cache mirror. This feature is available on Artica 4.30 Service Pack Instable 905 or Artica v4.40
For a full mirror cache, your server needs at least 120G of free space reserved for local repositories.
Artica uses a dedicated web service to provide the packages. This web server has been developed specifically for this purpose and only allows Debian update clients to download packages.
