Yesterday there was an IOSIOC reboot for a purpose. It was an opportunity to demonstrate to Controls that IOSIOC reboots materially affect the IOS section. Controls responded to an ICR fault report on it, and have not reported back to ICR so far. The source was off overnight and remains off now. I have informed ICR that if nothing happens this morning, I will restart the source after lunch.

Later... Jane reports that there was a problem, and it's been solved. We have to request that MCIS PVs get restored after a reboot. Done. Restart stuff. Much of IOS was already on.
