Silent VM Failures in Self-Hosted Infra Create Duplicate Network Services That Cause Full Outages
When a Proxmox VM hosting a DNS server fails silently and is later restarted, it can spin up a second DNS instance with the same IP as an already-running primary, causing total name resolution failure across the network. The absence of IP conflict detection and silent failure alerting in self-hosted virtualization environments makes this a recurring operational trap. 261 upvotes confirms broad resonance among homelabbers and small infrastructure operators.

surfaced semanticallySelf-Hosted Docker Infrastructure Fragile to Single Misconfiguration
Self-hosted Docker infrastructure is fragile and a single misconfiguration can wipe out running containers. Home server operators risk losing services during routine maintenance without adequate backup and recovery procedures.
Homelab Domain Incorrectly Added to DNS Blocklist Breaking Internal Services
A homelab operator discovered their internal domain was added to a third-party DNS blocklist (Hagezi), causing all self-hosted services to become unreachable. The incident was resolved by whitelisting the domain in Pi-hole. This is an individual situational incident rather than a persistent market gap.

Docker containers lose DNS resolution after host reboot due to stale resolv.conf
A long-time Docker user on Debian reports that after a host reboot, containers start successfully but cannot reach the internet because they fail to pick up the host resolv.conf; restarting the containers a few minutes later fixes it. This points to a startup-ordering race between Docker and the host DNS/networking services that surfaces only after a reboot, not during normal operation.
