Not completely, I'm not logged in on my work laptop and it was only working some of the time (and not like some pages were cached and some weren't, I was refreshing the same page and sometimes it worked and sometimes not).

If you aren't logged in you get a cached version from the CDN/cache. Reddit works the same way.

also went down if you went to login, and people's individual pages were also down. So as far as I saw the front page was up as long as you were not logged in, however I'm not sure if that wasn't just luck of the draw, I had one experience where it looked like maybe the front page was sometimes down for not logged in users as well.

on edit: ok others pointed out it was cached pages I saw. explains it.

That only worked for a while, eventually I couldn't load comment pages even logged out.

that'll be because it's served from cache when you're not logged in
