TUESDAY Sept 7, 2021 10:35 p.m. – In the event of a major solar flare, widespread blackouts could occur. This may last for weeks or even months.
A simple outage of the home internet for a few hours causes headaches for many users. Imagine if it lasted for weeks or even months. According to the researchers, it will be necessary to prepare for a long-term blackout on the Internet. If a major solar storm hits, the world’s electronic network could shut down for weeks.

So it should come as no surprise that electricity distribution networks are paralyzed for an extended period of time. In fact, wires carrying an electromagnetic signal are weak in the event of a large solar flare. Oddly enough, the local links provided by optical fibers are less vulnerable.
Scientists have estimated that cutting the Internet for a day in the United States would cost $7 billion. A large solar flare can be detected at the source, giving humanity about 13 hours to react.
The study concluded that submarine cables connecting continental networks would be particularly vulnerable, as would satellite links.
