Summary:

Around 5pm local time, the three vertex FEs crashed. AFAIK, no one was in the lab or working on anything CDS related, so this is worrying.

Details:

• Reboot script was used to bring all FEs back - only soft reboots were required.
• The IMC and arms can now be locked.
• I think combination of burt + SDF would have reverted all the settings as they should be, but if something appears off, it could be that some EPICS value didn't get reset correctly.
