I am running some services locally that I want to run local but when they go down have a way to switch over to digital ocean. Currently my DNS is through DO and I have credit on my account. I was thinking a floating IP (though I can't seem to assign them to my home IP) then direct that at my home IP and when my home server goes down, a DO snapshot would spin up and I could change the destination IP for the floating IP to that of the DO droplet.

Anyone have any ideas on how to configure this? Ideally I don't want to run a DO droplet all the time just when my home server goes down.
