There's not really any mention of other places after their books. The island in High Rhulain, the islands in Triss or any other islands really. I've slwaysviewed it as  communication just withering over time.

An isolated Abbey in the woods really has no need to communicate with anyone but its closest allies (Salamandastron, Guosim) for they can help defend it if it is attacked.
