Two locklosses last night:

2025-09-01 06:55 UTC - There is a possible MICH ringup of 1.6 Hz starting two seconds before the lockloss? Tagging ISC

2025-09-01 11:11 UTC - Earthquake. Seems like it was pretty large and local, so unsure if we would have survived it even if someone had used the ASC Hi Gains state
