The H1 system gave me a call this morning (~10:20 UTC 10/30), but when I checked the system in NoMachine, the IFO was at INCREASE DARM OFFSET and relocking and I couldn't find any issue (perhaps the timer ran over the limit?). However, once we got to NLN (10:26), I did see that the SQZ_MANAGER guardian was having some trouble, showing the warning, SQZ ASC AS42 not on??? in the guardian message log. It would cycle between this message and going back into FDS, so I hit RESET_SQZ_ASC before trying to go back into FDS, which looked to have solved the issue. - Tagging SQZ.
Tony and I looked into this and the reason Austin was called was that the IFO had been relocking for 2 hours so the H1_MANAGER's 2 hour "wait_for_nln" timer was up. The reason for the long relocking period was a lockloss at LASER_NOISE_SUPPRESSION 575 state 1382693851, Ryan had a lockloss here this weekend too 73787.
