Interesting choice in building this atop DigitalOcean. Not that it's wrong by any means, but I'd be interested in hearing what process you took in choosing them. (just curiosity)
I've said this before and time and time again, but I LOVE what they're doing over at RunAbove (OVH incubated). I'm not affiliated by any means, just a very, very very very very happy customer. The performance is unmatched and the price is so competitive!
