Can the Internet Survive A Cosmic Ray?

This week we saw the largest solar storm in nearly a decade and such “solar weather” or cosmic radiation is what generates such phenomena as the “Northern Lights”.

This has happened in the past, including grid failures in Quebec in 1989 which blacked out the entire province.
