Recently, the servers have been crashing constantly. I don't have any other information except for error 502. Can anyone tell me why?

It happened to me a few minutes ago, it's working now for me.

same here. I got internal server error and several 502 bad gateways.

Yeah, sorry about that! We tried to roll out some changes and it broke something so we had to back it out. It's a learning process.

Well thanks for telling what went wrong. That was not in a sarcastic tone. Trust me.
