Yeah, I'm on wi-fi and I thought it might be that, because I'm having the same issues today. Yesterday I kept getting that "bad gateway" error for a few hours. I'm used to that error, but I don't think I've experienced this delay before--or at least not in quite a while. At least it isn't minutes.
Edit: Whoops, spoke too soon. Just got the 504 error as I was trying to post this.
I'm wondering that this server down issue we're experiencing right now is somehow a effect of jamming the database just like what theymos have said the other day. Even though he fixed it already, I can say that it's not fully fixed by looking at the situation right now.
This might be the reason why the forum loads slower than before.
Some members also said that they've encountered this 504 gateway timeout error after the problem that day.
At the other side. I'm sure that Admin are working on it silently.
Oh by the way, here is the topic I'm referring to

Hmmm, so it's really something unusual.
