Have had a lockloss and struggling to lock again. This may be because as we have a lot of ground movement at EY from the wind fence work.
19:27 Lockloss. Wind fence work is ongoing at EY, with the ground being "smoothed". Imagine this is the cause.

One of Camilla's locklosses in this recovery (from Low noise ASC) looks pretty similar to one that's we've been having frequently where there is a sudden burst of high frequency noise in DHARD that saturates many supensions. This one is interesting because there are several ADC saturatoins at the time of the DHARD problem, as the lockloss website shows: 1257975934. There seems to be something wrong with the subplots that would help us narrow down which channel was saturating though.
It also looks like inthe seconds before that lockloss we are having the problem with the PSL rotation stage where it jumps back, see 53068
