Anubis, the instance's anti-bot system, seems to be working, so issue's a bit after that I'd imagine.

Also tested across multiple browsers, devices, VPN servers, a real IP, with and without login... Appears down in general.

I also noticed a few other sites I keep as homepage tabs on my browser were struggling to load, including Cloudflare being far jumpier than the usual, so I wonder if it's related.
