Your system struck by lightning? What did you learn?

Unplug during storms.

I have whole house surge protection and my power conditioners have surge protection, however when we get real bad storms with lots of lightning I unplug my 2 systems

Synology HD.  PIA, it has the OPSYS on it.  Put it on a sacrificial. Good enough.

I had a ground-fault catastrophe.  It destroyed every SS piece of equipment that was hooked up (two cd-players, a sub ... [along with the oven fan; the coax cable for internet melted]).  Tube equipment SEEMED unaffected, but a blown capacitor showed up later in the summer in one of my amps--I assume that's what caused it.    I also had a lightning strike years ago that took out my VHS (not anything in my sound system).   What struck me as odd is in neither case did a circuit breaker blow; and in none of the burnt out equipment did the fuses blow.  Maybe someone w/ more expertise than I have can explain why not? (I didn't really expect a tiny fuse would stop a lightning bolt that had already travelled five miles to my house, but I wouldn't have expected it to survive either.)
