Bloopist was down unexpectedly for about 21 hours from 11:54 pm (on 11/15/2015) to 8:15 pm today (11/16/2015) central time.
Bloopist is hosted on an Amazon EC2 instance. The hardware that the instance was running on broke without warning. The server stopped responding to the Pingdom monitoring service at 11:54pm, and i recieved an email from Amazon notifing me of the "degradation of the underlying hardware hosting" Bloopist.
If you're interested in seeing what the email that Amazon sends you when you server dies looks like, I've embedded a snapshot of it below:
