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.
