Zones of south of chile without images

Hi, I have some problems with images in the south of Chile, the last imagen available is june 10…Do you know when this problem is solved and the satellite will take images again?
Will it be possible for the satellite to stop taking images of an area?
How to know if it is a small problem in that latitude and in the near future will continue to take data?
Is it possible to know in advance when this problem will occur again?
and in what places of the world?
Thanks in advance, Sandra Fredes

In case you are talking about Sentinel-1 images, you can have a look at the Acquisition segments defined here:

You can download a kml file which shows you the images to be acquired in the near future.
