So I decided to try to run a Pub server the other day. Unfortunately, it turns out that the state of the pub servers is rather poor right now. Not that they won't work, but simply that the maintenance and work to get one up and running reliably right now is a lot more work than I anticipated. Fortunately, no one needs to run their own pub to use Scuttlebutt or Patchwork.
Mine appears to be running reliably now at social.sacrideo.us but that's only appearances. I'm hoping that they'll get the memory leak issues figured out soon.
