DNS / Service Discovery Notes

  • internal.zlh is not currently used for active hot-path service discovery
  • Prefer explicit env-configured IPs / addresses in runtime-critical paths
  • DNS records may still exist historically or for reference, but should not be treated as the current source of truth for service routing

Backup Strategy / Ownership Boundary

  • PBS (zlh-back, 9017) is the infrastructure backup layer for VMs/LXCs
  • offsite durability/sync belongs to the PBS/platform layer, not the agent implementation layer
  • agent-local Minecraft backups are app-aware rollback backups inside the workload/container scope
  • do not treat platform/PBS durability work as agent backup implementation work unless ownership changes
  • Old Denver host decommissioned Apr 2, 2026 — OS wiped, disks striped
