Satellites in geo-synchronous orbit are there for 100s of thousands of years.
They all spin around the earth in the same direction. One of the future threats of islam is that they could launch a load of shrapnel in geo-synchronous orbit going the wrong way which would quickly destroy every satellite in that orbit with no hope of using it ever again.
Covering the orbital swath (thousands of square miles) with enough shrapnel to have a one in a million chance of hitting a satelite would be very tough. Don't sweat this one.
