My PC supply blows some Varistors in a huge strike about 50m near my building.

Just on time and  I lost most everything

After that  I added a whole house surge protection at my side of the meter and I then ramped up the rest of my surge equipment.    And then imoved from the thunderstorm and tornado ridden Kansas to the land slides and wild fires of Oregon.

A loooooong time ago on planet Vietnam lightning stroke the 12Kv line across the street
and the voltage surge blew up my modem.

Could possibly be a voltage dip rather than a spike, caused by a ground fault somewhere upstream.

Voltage dips don't damage electronic equipment.

A whole house surge protection system is the way to go.
But lightning spikes can still sneak in through the telephone, cable TV or satellite TV wires from outside.

Nothing was said about equipment damage, only that it wasn't operating correctly at times.

That's not how I read the original post.
