It is still maintained, at least by me when I notice it is down. It appeared that /var/log on ws-web filled up with lots of daemon.log.x files (9 GBs worth). I believe this caused the process to stop, and for it to not be able to restart.
I cleared out the logs, and restarted the service. I was confused with the /etc/init/wikistream.conf file appeared to have been removed, which I've used in the past to start/stop the service. Fortunately I had a copy in the github repo for the project https://github.com/edsu/wikistream to easily put it back. If anyone has any insight into why it was removed I'd be interested to hear it.
