Hi all – I had about 30 minutes of downtime yesterday with my DigitalOcean Droplet install of Discourse (as measured by external monitoring via Pingdom), and am wondering what the next steps are to diagnose and prevent recurrence. What I’ve observed so far: My Discourse install is 1.9.0.beta13. …

The stacktrace has to do with Discourse not being able to talk to your SMTP server. Since this is done in a background job I don’t think this is what caused your downtime.
