I came in to check the status of the nitrogen and noticed that the striptool panels in the control room were all blank.

• PMC was unlocked but I was able to relock it using the usual procedure
• FB seems to be down: I was unable to ssh into it (or any of the FEs for that matter). I checked the lights on the RAID array, they are all green. I am holding off on doing a hard reboot of FB in case there is some other debugging that can be done first
• None of the watchdogs were tripped, but judging by the green spots on the mirrors, all of them are moving quite a bit. I've shutdown the watchdogs on all the optics except the MC mirrors, but the ITMs and ETMs still seem to be moving quite a bit.

I am leaving things in this state for now. It is unclear why this should have happened, it doesn't seem like there was a power glitch?
