Designing high availability around a VPS
One VM is not HA. Redundancy lives in DNS, a second region, and tested failover.
A single Noble VPS can be very reliable and still be one failure domain. True HA means a second instance, health checks, and a failover you have rehearsed.
Put the primary in USA or EU near users. Keep a cold or warm spare in the other region if downtime is expensive. Use health-checked DNS or a reverse proxy. Store state (database, uploads) where both sides can get it, or accept a promote-from-backup RPO.
Automation that rebuilds from images beats a heroic SSH session at 3am. Our status page tells you when a node is down; it does not fail you over.
