I just changed something, maybe that'll help.
If people still get it, please post:
- Exactly the time you saw it.
- The footer of the error message (eg. "504 via master1")
I got
504 via gate24 most likely a minute or two before posting this comment. It seems that this Busy try again page shows frequently these past few days.
Edit:
* Encountered the same error again between 3:19 PM - 3:25 PM forum time
* 504 via gate105 Aug18 10:28 AM
* 504 via gate22. Aug18 10:40 AM don't know how long it lasts but I was back online at 11:06 AM
