Lockloss
Lockloss at 2025-06-23 19:58 UTC. A commissioner was running a jitter noise injection at the time of the lockloss, but doesn't think that was the cause of the lockloss.

The DARM signals look very noisy just before the lockloss because I was injecting jitter noise. I don't think that caused the lockloss. The tool is tagging this as "ETM GLITCH" which I also think is wrong because the extra noise was bringing the DARM signal above threshhold for the glitch checker.
