Update (1hr later). Site is back up! I wouldn't be surprised if there were other blips over the next day or 2, but hopefully they will be just as short-lived.

The site is currently down for all unfortunately. The hosts are aware, and are working on it, but I have absolutely no idea if we are talking minutes or hours here.
If you get 522 (or any other 5xx error) please just try again in a few hours. No point trying to connect with a VPN or any other way. I will update this post when we are back.
😢

In a little bit of good news, in the hours before this current outage, several of the previously blocked locations were able to connect again, indicating that the re-routing was finally getting through. Fingers crossed that this will remain so once we are back online!
