Out of Observing from 12:11-12:13 UTC
Unknown cause. I had stepped out of the control room and noticed it was in Commissioning upon return. No SDF diffs. There was a notification on Verbal Alarms of an EX saturation at 12:10 UTC. I had earlier noticed the scheduled injection running at 12:00 UTC in the DARM spectrum. Lock is now 10 hours young.
There is a distinct line of glitches noticeable in the DMT Omega FOM that lines up approximately with the loss of Observing.
The IFO Guardian node reported SDF diffs at that time. DIAG_SDF node reported susitmy, susetmx, and susetmy diffs with 15 seconds of each other then.
