-What it is: mutual automatic failover between two independent unRAID servers. When one goes down the other starts its containers, cuts over DNS, and keeps users online. When it comes back, everything hands back in the correct sequence — DDNS stops, containers stop, rsync writeback runs, containers start on the primary, primary DDNS starts last — so users hit the returning server only after it's actually ready.
