No obvious cause, but the wind had recently picked up and looks like there was an ETMX glitch immediately before the lockloss.

H1 back to observing at 23:10 UTC. Longer acquisition due to lots of low-state locklosses with seemingly no explanation (e.g. ALS dropping out unexpectedly for both arms). Eventually issues resolved themselves and relocking went automatically.
