The PSL was taken down 6 days ago for a Beckhoff update (alog76879), which is seen on several trends.
After that, the PMC seems to have locked with lower transmission by almost 1W.

SHIFT SUMMARY: Mostly quiet day with just one lockloss and a fully automated relock. The network has been down all day and came back at 22:48 UTC.
LOG:
No log for this shift.
I restarted the lock_loss_alerting system at 19:59, it had not been running correctly following the network outage.
Lockloss @ 17:52 UTC - no obvious cause. There was a small spike in the EQ band at EX around that time, but I don't expect something that small would cause a lockloss.
H1 back to observing at 19:02 UTC.

The spectra of CS_ACC_LVEAFLOOR_YCRYO_Z, CS_ACC_HAM3_PR2_Y are much lower than the other accelerometer channles.
(i) The channel CS_ACC_LVEAFLOOR_YCRYO_Z has been like that since March 12.
(ii) The channel CS_ACC_HAM3_PR2_Y has been like that since Jan 30.
It seems they are either disconnected or having a lose connection.

SHIFT SUMMARY: Currently Observing and have been Locked for 3 hours. Lockloss earlier in the evening needed me to adjust ALSY and move the beamsplitter for MICH/PRMI/DRMI but we went up quickly after that.
LOG:
23:00UTC Detector Observing and Locked for 7.5 hours
02:47 Lockloss
- ALSY had really high flashes but was struggling to catch until I bumped the flashes up by ~0.02.
- We ended up going through CHECK_MICH_FRINGES but I was able to get us aligned enough to go through DRMI without needing to do an initial alignment - we'll definitely need to run an initial alignment next time
