I came to the control room and found the PMC and IMC were unlocked. ==> Relocked
I found the watch dogs of the vertex suspensions are tripped.
I checked the data for the past 6 hours and found they are independent events.
The unlock of the MCs occured 4 hours ago and the watchdogs tripped 2 hours ago.
The suspension damping was restored at around 7:50PM PDT.
Oops, I should have noticed all of those things. Several hours of computer-battle exhausted me. Thanks Koji.
