What does that mean?

Go read https://www.digitalocean.com/business and https://status.digitalocean.com/ if that doesn't put you at ease send them an email.

However it shouldn't matter. Droplets are essentially just on demand "vps's" most of the operations work is done by your operations team(in this case I imagine this is you). Where your hosts(machines, containers, vps's whatever you want to call them) are shouldn't matter very much, what is important is that you have repeatable infrastructure, so that when you spin up a new VPS anywhere(AWS, DO, Vulcan, Your Garage) you can get up and running again fairly quickly.
