The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfill the request.
Hopefully Simon sees this, because I know for a fact this happens every day multiple times, and it gets super annoying after a while. It's been happening for months now, and it didn't used to before.
The entire website and game just stop working for a minute or two. I know one problem used to be something with the wiki, Simon said he fixed that last time I told him.
@mniip(View Post) lol. Although the rumor that it's IP graphs causing it isn't actually true, I once rendered a huge one and checked $justme, it said the website was still up. I think users are limited to two requests at a time, so ip graphs just fill that up and prevent you from accessing the website until it's done.
Oh, also I think in game still works when an ip graph is lagging you.
