All signs point to #NaNoWriMo shutting down, apparently according to an email they sent out (I'd closed my account). I don't see anything on their site yet, but they do appear to have shut down their help desk.
First, I want to say that while the last two years from them have been especially disappointing, I'm grateful to NaNoWriMo for being one of the influences that first inspired me to take writing seriously.
Second, I want to remind people that this last November I launched an alternative, #WritingMonth.

The initial development round was very rushed to get it out by November, but I plan to launch a full second development round starting in May, so we can have a much more complete finished product for this fall.
I also have Writing Month stickers, which I'm currently thinking I'll send out to code contributors who want them, at the end of the summer. I'll send pics when I have a moment.
