Services
Each service is run within either a vm or a container. This is both for security, but also for easier resource redistribution.
web-server: Apache2, MariaDB and PHP 5.6+. Have some domains there, but even more sub-domains, which most of them are linked to other services. Certbot is used to generate certificates for the (sub)domains that need it. Mirror can be found here.
minecraft-server: MCJE and MCPE/BE.
teamspeak-server: Can handle up to 512 users, but normally does not reach more than 30 at the same time.
gitea-server: An ordinary gitea-instance for private content versioning.
factorio-server: Two instances currently.
ttd-server: An OpenTTD server.
blockland-server: Hosts a couple of Blockland instances.
brickadia-server: Offline instance.
mastodon-server: Private instance.
pihole-*: Pi-Hole for internal filtering. Two instances for redundancy.
ddclient-*: For dynamic dns handling.
syncthing-disco: Discovery and relay server for SyncThing.
prometheus: Monitors all servers and services.
grafana: Graphs for prometheus.
Besides these there is a lot of test vms/containers and private instances that are kept a secret.
