I lived in a Caribbean country where, at the time, most of their LD traffic was over satellite. While people didn't like it, there were times that there was no public off-island access for a few hours at a time. It's just a fact of life, and people get used to it. Those who don't buy a satellite phone.

The "orbital last mile" for individual users as well as in-country (Africa for e.g.) ISPs and Enterprise networks. When they go, often there is no backup (except maybe another satellite connection).

But that is merely my two cents worth.Yep, consider the Galaxy IV satellite incident. The loss of a single satellite had a significant impact on its user population for several days/month. Other satellites can be moved into an orbital slot, and dishes can be re-pointed; but Galaxy IV lead to some interesting (i.e. unexpected to some users) failures. I'm not sure how many hospitals realized their "in-house" pager systems relied on a satellite.
