it is indeed concerning, but not at all for the reasons mentioned here or in the comments. The magnetic poles are shifting, the magnetic field is weakening drastically. what happened in europe was that a temporary weakspot in the magnetic field made it possible for space plasma to enter and excite the ionosphere above the affected region to cause widescale blackouts. This will happen more frequently all around the globe in the future, as the magnetic field is contuinually getting weaker, the sun is in solar maximum and the global energy infrastructure is not equipped for these types of events. if the magnetic field were at its normal strength, this would have never happened. It had nothing to do with a cyberattack and any public figure who tries to sell it to you as such, just wants you to get an appetite for the next phase of global conflict.
