-# ssh.socket Unreachable After Reboot (Tailscale Race Condition)
+# Tailscale Boot Race Conditions (SSH Unreachable After Reboot)
 
-## Symptom
+Two related race conditions can make a host unreachable via Tailscale after reboot. Both stem from systemd services starting before Tailscale or the network is ready.
+
+---
+
+## Race 1: ssh.socket Binds Before Tailscale Is Up (Ubuntu)
+
+### Symptom
 
 SSH to a host via Tailscale IP times out. `tailscale ping` works, `tailscale status` shows `active; direct`, but SSH on port 22 refuses connections. No access via Hetzner console if root password is unset.
 
-## Cause
+### Cause
 
 Ubuntu 24.04 uses systemd **socket activation** for SSH (`ssh.socket` instead of persistent `ssh.service`). When the socket override binds to a Tailscale IP, it can start *before* `tailscaled.service` is ready. The bind may succeed initially (Tailscale state file caches the IP), but a later Tailscale reconnect or interface reset invalidates the bound address silently — SSH dies with no recovery path.

+### Affected Hosts
+
+Ubuntu hosts using `configure_tailscale_ssh_only.yml`: majorlinux, dcaprod-hetzner. Fedora hosts (majordiscord) use firewall rules for SSH restriction — not affected by this race.
+

+
+## Race 2: tailscaled Starts Before Network Is Online (All Hosts)
+
+### Symptom
+
+Host reboots but never appears on Tailscale. `tailscale ping` times out entirely. SSH is dead because Tailscale never connects. The host is up (accessible via provider console) but isolated from the Tailscale network.
+
+### Cause
+
+`tailscaled.service` ships with `After=network-pre.target`, which fires *before* the network interface has an IP. On VPS hosts (especially Hetzner), the interface can take several seconds to come online. Tailscale starts, sees no network (`SetNetworkUp(false)`, `link state: defaultRoute= ifs={} v4=false v6=false`), fails DNS bootstrap and DERP relay connections, and gets stuck — never retrying.
+
+### Diagnosis
+
+```bash
+# From Hetzner console or another access method:
+journalctl -b -u tailscaled | grep -E "SetNetworkUp|link state|error|DERP"
+# Look for:
+#   magicsock: SetNetworkUp(false)
+#   link state: interfaces.State{defaultRoute= ifs={} v4=false v6=false}
+#   health: Tailscale could not connect to any relay server
+```
+
+### Fix
+
+Deploy a systemd drop-in to wait for full network connectivity:
+
+```ini
+# /etc/systemd/system/tailscaled.service.d/override.conf
+[Unit]
+After=network-online.target
+Wants=network-online.target
+```
+
+Then reload and restart:
+
+```bash
+systemctl daemon-reload
+systemctl restart tailscaled
+```
+
+### Affected Hosts
+
+All hosts where Tailscale is the primary access path. Particularly impactful on VPS hosts with slow interface bringup. Both Fedora and Ubuntu hosts are affected.

 ## Prevention
 
-- Set root passwords on all Hetzner hosts for emergency console access
-- Ansible playbook `configure_tailscale_ssh_only.yml` includes both directives as of commit `7ef182b`

+- Set root passwords on all VPS hosts for emergency console access
+- Ansible playbooks deploy both fixes automatically:
+  - `configure_tailscale_network_wait.yml` — tailscaled network-online dependency (all hosts)
+  - `configure_tailscale_ssh_only.yml` — ssh.socket Tailscale dependency (Ubuntu only)
