CMEs cause very long-length disturbances so you need a conductor of quite a length to cause problems. The power grid is one example. Anything that’s on a solar panel and not connected to the grid would not be a problem because the wires are much shorter and don’t have enough space with which to build up a charge.
You seem to think the entire world is connected by fiber now. Not the case. 98% of long distance cable runs across the world are still air run copper. That won’t immediately impact high dollar facilities like datacenters or undersea cables that are interconnected, but everything else it will take a hit.
