While fiber optic cables themselves are largely immune to GICs, the power infrastructure that supports internet connectivity is vulnerable. Disruption to power supplies at data centers, network exchanges, and even individual homes can lead to widespread internet outages. Solar flares can disrupt internet infrastructure through several distinct mechanisms: Ionospheric Disturbances and Radio Blackouts: X-ray and Extreme Ultraviolet (EUV) radiation from solar flares can significantly enhance ionization in the Earth's ionosphere. This increased ionization can absorb. These geomagnetic disturbances are visible in polar skies as Aurora Borealis and Aurora Australis, nature's most spectacular light shows. Their beauty notwithstanding, solar storms may have equally dramatic and potentially destructive effects: they can induce extreme voltages in electric wires. Solar radiations affect the total electron content of the ionosphere that may disturb the radio-frequencies used in telecommunications. However, this vital infrastructure is not impervious to external threats.
