I just created a droplet today, and was trying for the life of me to figure out what I would have done so early on in setting it up to cause it to become unresponsive. Glad to see it's not just me. It's not really a great sign though, as I was hoping to use this fairly frequently. Is this a common occurrence, or do I just have bad luck? If so, I'll definitely have to find another solution.
That being said, near 100% uptime is really desired in this space and I've been scratching my head for the past hour or so wondering why I couldn't connect to my mongo process running on my droplet...maybe I should have tested DO sooner, but the fact that only mongo seemed to be failing (and not postgres for example) made me think I had client and not server issues.
