The company I work for has to deal with satellite outages twice a year that we can do absolutely nothing about.

Help page from a satellite provider

Our individual downlink sites, because of their small dish size, are completely blocked out for a few minutes each day while this happens. Our large uplink dish has a lot of power behind it, so it only experiences severe signal degradation rather than a complete outage. Unfortunately this means that a large percentage of our downlink sites (those that are not in the center of the satellite footprint) get to deal with two outages per day – once when they line up, and again when our uplink lines up.
