We operationally process Sentinel 1 (A and B) data over our area. First step we do is slice assembly. We are experiencing problems with data after 12th march 2018.

If we try to apply the same process, to data acquired starting from 13th march 2018, the processing fails. We have reprocessed some previous data and the processing is succesful.
