Lockloss at 10:08 UTC

A pair of DCPD saturation alarms preceded the lockloss.  No apparent environmental cause.

I had a quick look at the lockloss tool and it looks like ~10 seconds before the lockloss there is a glitch that saturates the DCPDs, then the ASC runs away perhaps because the ADS lines got drowned out? Maybe we need to set something up such that if there is a glitch the master gain of the ADS gets turned to zero for a second?
