I am living in Izmir (Turkey), I was getting combination of Pakistani channels and Indian channels on Astra 2 satellite. I have a 1.3 m satellite and C band LNB. For some reason these channels stopped coming.
My satellite operator tried everything, but to no avail.

My questions are is it normal for channels to be updated periodically, and channels you are watching may suddenly disappear. or the polarities of the channels can be changed.

Does somebody have information about Astra 2 satellite, or is there some other satellite in on which pakistani and indian channels are available in turkey.
