For background, Reddit fired a (the?) community manager, leading the /r/IAMA mods to set their sub to private and post on /r/OutOfTheLoop that they were blindsided by the decision, and were left without critical support for their AMA efforts.
A few hours later, and as of the time of this post, /r/science has been set to private as well. /r/science, unlike /r/IAMA, has links and self-posts, but also has an AMA component, which the community manager in question would've helped to coordinate.
The access denied page says:
Due to an unexpected Reddit administrative personnel change /r/science is temporarily private so that we can resolve the situation, our apologizes for any disruption this may cause.
