-After a boot, the encrypted root partition will have to be unlocked. This is done by accessing the server via SSH with user root on port 2222.
+After a reboot, the encrypted ZFS pool will have to be unlocked. This is done by accessing the server via SSH with user `root` on port 2222.

+Nachtigall:
 
 ```
-ssh root@nachtigall.pub.solar -p2222
+ssh root@138.201.80.102 -p2222
+```
+
+Metronom:
+
+```
+ssh root@49.13.236.167 -p2222
 ```
 
 After connecting, paste the crypt passphrase you can find in the shared keepass. This will disconnect the SSH session right away and the server will keep booting into stage 2.
