Lockloss

Lockloss @ 10/15 04:38UTC

We were staying locked through an earthquake but got the DIAG_MAIN message: SERVO_BOARDS: IMC-REFL_SERVO_SPLITMON > 8V at 04:25 and then multiple times and more often in the last few minutes. SRM was constantly saturated in the last minute of the lock. T1 is where DARM_IN1 gave out.

Because ground motion is still very high and we will need to do an initial alignment, I'll be holding us in DOWN for at least ~10mins
