Hi all.
So I’m pretty sure outside of the managed database instances, there’s no standby nodes.
However, I’m looking to confirm another few aspects. If the hypervisor our droplet is on goes down/crashes/hardware failure, does the infrastructure automatically spin up a new droplet for us, porting over our entire droplet, IP, etc? In other words, droplet/hypervisor is running great, all of a sudden a NVMe failed; outside of the time it takes their systems to “realize” it crashed and such, would everything spin back up on a new node without any interaction from us?

Hi there,
You are generally right. Standard Droplets do not have standby nodes like managed databases.
If a hypervisor has a hardware issue, DigitalOcean automatically attempt to recover the Droplet by restarting it on healthy hardware and keeping the same disk and public IP. In most cases I believe that this happens without user action once the platform detects the failure.
That said, I guess that recovery timing can vary. Because of that, it is best to treat single Droplets as non-HA.
If availability matters, the safer approach is to design for failure using multiple Droplets, load balancers, backups, and snapshots, rather than relying on hypervisor-level recovery alone.
