That looks nice until it doesn't work. We regularly see 30 minute event processing when doing flexible upgrades of Droplets (and the same when scaling back down). It's not safe, since the resize isn't guaranteed to be fast and you have no way to abort it once it's started. Sounds good in theory, not reliable enough to use in practice.

Isn't this what the flexible IP is for?

You create a new droplet concurrently the one running and then flip the IP to point to the new droplet. No downtime.

You have to have the a server with the same configuration or a snapshot or provision a new one...
