Fedia.io should be stable now
After I resolved the federation issue, I had to clean up a few things and so the site may have been unavailable for a bit. I'm done fussing with it and will keep an eye on it to make sure things are working.
IF YOU SEE PROBLEMS - please let me know. As far as I know, I've fixed all of the federation and error 500 issues we've had, so please don't assume it's just more of the same if you see them.
Thanks for your patience.
