Never a dull moment in the home lab....are you ready for a power failure?

Had an uncharacteristic power failure here on Friday, of course right in the middle of a conference call. Everything came back to life eventually, with only minor glitches.

1) I discovered I plugged my router into one of the 2 unprotected sockets of my UPS. Sigh. Ever wonder why we do disaster recovery testing on a regular basis in industry? I should know better!

2) I have  RPI4-8, Nano-2g and T1700 Win10 connected via a KVM switch. I discovered they like to be rebooted while set to display via the KVM switch. So, even though they were all alive, I had to reboot them 1 by 1 to get full switch functionality back.

3) The Dell T1700 workstation was the only "victim". Got flashing light warning signal with when I resorted to Google, it indicated a motherboard issue. Happily, I removed memory and rebooted getting the expected error beeps. Reseating the memory worked, all back up and running.

My RPI4-4 development workstation came back to life gracefully (it runs from SSD) as did the RPI3B+ which uses a micro SD card (Octoprint).

So presumably you had a spike as well, when it came back?

@michaeldk I seem to recall it took 1-2 tries for power to come back completly so probably "yes" there was a spike.
