Hello everyone,
Hope you're enjoying the current season!
Just a small update for anyone who's wondering why the site was down for about 24h until just moment ago. Thank you very much to the user who contacted me about the error!
For some reason, Apache lost communication with Passenger (the Ruby on Rails library used by this site) causing the "403 Forbidden" errors we were seeing. The logs show an update triggering a Passenger restart, which for some reason failed. A server reboot seems to have resolved it for now, and everything looks fine. I'll keep an eye on the issue, but otherwise I'll have to blame it on cosmic rays.
If you notice any issues (including, but not limited to "403 errors") please let me know, and I'll take a look as soon as possible. As always, you can send me an e-mail at 
(the e-mail servers are not self-hosted, so they should work anytime, even when the site is down).
Thanks! (and sorry for any inconvenience)
