Fehler 502 Bad Gateway auf meta.discourse.org

Was trying to post a new question (topic) a moment ago and I got that error. What does that mean?
Btw I tried posting again after a moment and it worked.

Where did this happen, it generally means there is some sort of transient network or server error.

I was here posting a question about tags.

Thanks

Oh, meta is deployed very aggressively with every public github checkin, so that’s not terribly unusual here.
