There was a power outage ~30 mins ago that knocked out CDS, PSL etc. The lights in the office area also flickered briefly. Working on recovery now. The elog was also down (since nodus presumably rebooted), I restarted the service just now. Vacuum status seems okay, even though the status string reads "Unrecognized".
The recovery was complete at 1830 local time. Curiously, the EX NPRO and the doubling oven temp controllers stayed on, usually they are taken out as well. Also, all the slow machines and associated Acromag crates survived. I guess the interruption was so fleeting that some devices survived.
The control room workstation, zita, which is responsible for the IFO status StripTool display on the large TV screen, has some display driver issues I think - it crashed twice when I tried to change the default display arrangement (large TV + small monitor). It also wants to update to Ubuntu 18.04 LTS, but I decided not to for the time being (it is running Ubuntu 16.04 LTS). Anyways, after a couple of power cycles, the wall StripTools are up once again.
