SUN STOPS SATELLITE SIGNAL

My satellite television signal has been pretty stable in recent weeks, but yesterday it disappeared totally several times and was replaced with the message pictured right.
Have you ever heard of a 'sun outage'? I must admit I hadn't until yesterday, but a quick look at Wikipedia came up with the following:
-----
A sun outage is an interruption in or
distortion of geostationary satellite signals caused by interference from solar radiation. The effect is due to the sun's radiation overwhelming the satellite signal. Generally, sun outages occur in February, March, September and October, that is, around the time of the equinoxes. At these times, the apparent path of the sun across the sky takes it directly behind the line of sight between an earth station and a satellite. As the sun radiates strongly at the microwave frequencies used to communicate with satellites (C-band and Ku-band) the sun swamps the signal from the satellite. The effects of a sun outage can include partial degradation, that is, an increase in the error rate, or total destruction of the signal.

It all sounds pretty dangerous and I hope I don't suffer from partial degredation too.
