It is amazing that the "developists" in highly developed places forgets that the world is far from being equally developed and connected, with high speed digital repeater networks, easily accessible Internet, etc, etc...
Even more, that you don't have to go to Asia, Africa or anywhere in the Third World to find it the same case... Towers may fall...fibers may break (it happened recently in the US west coast), etc, etc. We have had that scenario here in my country several times this decade. In the middle of a category 5 hurricane, only HF works...who is going to keep a satellite dish properly aimed in such a situation? Satellites have to be substituted periodically, in no more than 10 years periods. How many times has the ionosphere been substituted since 1900 ? None, that I remember.
