If you notice channels being briefly interrupted, it could be from a solar outage. Twice a year, around October and March, the sun aligns so that TV satellites are directly between the sun and the receiving dishes. The sun’s rays overwhelm the satellite signal, causing brief outages for about 10 minutes per day for about a week. The time of the outage varies by which satellite a channel is using, but they are generally during the day. During Sun outages, you may experience short interruptions in service such as pixelated or fuzzy picture, picture freezing, or audio issues.
