Solar storm could kill global internet for months — study

A massive solar storm could disrupt the Internet for months, especially affecting undersea cables. While optical fibers are safe, electronic repeaters are vulnerable to damage. Regional networks might recover quickly, but international connections could take weeks to fix due to the complexity of replacing oceanic repeaters. Research by Assistant Professor Sangeeta Abdul Jothie highlights the need for further study on solar storm impacts on underwater power systems.

Why would international Internet connections take longer to restore compared to regional grids after a solar storm?

What further research is suggested regarding the effects of solar storms on power systems under the ocean?
