I was just now watching this graph instead of the reddit page (its a little more intriguing for some reason) and I just about flipped out of my chair when out of the corner of my eye I started noticing an orange, then red, then blue bar .. did your backend server lose the websocket, or something, just now? Because frankly that was one of the most exciting things that has happened to me on the Internet in the last 24 hours .. ;)
It connects directly to the reddit's websocket... What you saw was the app not handling onclose/onerror... Which I'll get around to implementing one day.
