Occasionally the Celery workers that power WikiWho will go down, because we start it using init.d. When it dies, it must be manually restarted. We should move them to use [[ https://en.wikipedia.org/wiki/Systemd | systemd ]] instead so they are auto-restarted.
===== Original report
**Steps to replicate the issue** (include links if applicable):
* Go to any Wikipedia article, e.g. (from clicking the random article link), https://en.wikipedia.org/wiki/Spaatz_Island
* Click "Who Wrote That?"
**What happens?**:
Chrome thinks for a while (with blue banner showing), then replaces it with a red banner saying, "Error: Refresh or try again later."
**What should have happened instead?**:
Chrome thinks for a while (with blue banner showing), then banner changes to say that Who Wrote That is in effect.
**Other information** (browser name/version, screenshots, etc.):
I'm using Chrome. I could reproduce this on both Windows and Chrome OS.
