Two major subs called /r/technology and /r/programming just went dark. This seems to have reached great levels now considering that CEO /u/spez himself is a senior mod on /r/programming sub.
At this point, I think the most visited and interesting subs are already down on reddit, love to hear any exceptions which are still up and running.
Also /r/technology and /r/programming went dark only after lot's of pressure from all sides and other subs.
