Locked in Observing mode for 2.5 hours.  Some hardware injections have taken place, but are done for the evening. 

I had to restart the graceDB querying between injections.  I'm not exactly sure when this failed, but I stumbled across it while doing my usual operator surveys.  Had I not had the injection control window open, I would not have known that querying had failed.  Perhaps we should put an alarm in Guardian that lets us know querying has failed and needs restarting.
