Ed, Patrick

14:50 UTC The IFO lost lock. Guardian reported ISC_LOCK node in error and LOCK_LOSS_SHUTTER_CHECK node in error. The guardian overview turned dark red. I hit LOAD on the ISC_LOCK guardian. Ed came in and I turned around and saw a bunch of frontend models were white. I thought it must have been a power glitch, so I called Richard. He reported that he did not receive any notices related to a power problem and suggested I call Dave. I have done so, but have not been able to reach him yet. I am no longer thinking it is a power glitch. The laser is still up and all of the machines in the MSR appear to be running.

I have attached a screenshot of the initial guardian error and the cds overview.
