It appears the lemmynsfw is gone.
There were only two people involved with the server, and only one of them had the keys and even the most basic information about the hosting. That person has been MIA since October.
Given that only a single person had any access and knowledge of the infrastructure means that this was inevitable.
It solves the problem of "where do we go now that [X] is fucked up?"
Anyone with the means can make a LemmyNSFW2.0 and carry on after hitting this bump in the road.
If it was a proprietary privately owned site, you would have to do a lot more to duplicate it.
This is less like Reddit going down and more like a single, specific page on Reddit not opening correctly.
