Definitions are tricky --- It is difficult to ascertain what are society's vital functions. Some of them are perhaps "evident", like protecting basic infraestructure, including energy, power generation and water supplies. However, it is clear countries will draw the line in different places, since each country will evaluate differently what is "vital" for them. Also, sadly, that determination varies in accordance with the level of development of that nation. Whereas developed nations will consider access to internet as such, others, poorer, will only include water and food supplies, for example.
