The Moment of Truth October 17, 2013
Every morning I have an email from pingdom that my site went down overnight. I've upgraded to node.js 0.10.20 a few weeks ago to take advantage of some other bug fixes and optimizations, and it shows in the Google Analytics page load times (they're all 0 seconds)
I have had no luck tracking down the cause, but I read about how to prevent a server error from bringing down the site. I've implemented the suggested solution using node.js domains, and we will see what's happening tomorrow.
It might be the same thing because when I go into the server, node is still running my webserver, it just appears the socket was destroyed... We shall see. Wish me luck!
