I doubt they are. While DO boxes aren't bad, in terms of the "bad neighbor effect", I think they very much are oversold. Also, the virtualization tech is a continuum between complete and proper isolation of resources and time slicing of the CPU cycles on the one end, and Linux container style resource sharing on the other. Basically, the more isolated your VM is, the slower it will run. I don't believe DO is using any type of really strong isolation. Because of this, if you start mining BTC on your droplet, you will suck the CPU cycles from all the neighbors.
