Kudos to all lecturers!
My university already had a very good platform for online learning, and I was impressed how quickly we got information from the professors how classes will proceed (lecture casts, more homework etc.) Easier with some than with others, of course, and I probably don't want to know how it looks behind the scenes... I hear rumors other universities in Vienna are struggling much more, because they have very little existing infrastructure for a distance set-up.
