Filed as a support ticket poked for this.
Users would like a slightly better help page for when there are operations issues like 502/3s.
While the ticket requested more details on the issue, it's not really possible to throw up the exact error as the logs often don't show it. Then there's the issue of getting that log entry.
So we'll keep a generic "server went away" or something like that. Should be simple, but with a bit of colour and a bit of text. Might be worth throwing a link to the blog or social media in there as well to keep people up to date?
