After going through the publishing error logs, I see a handful of publishing failures because of the following reasons:
- The user is blocked from editing in the target wiki
- The content has URLs that triger spamblacklist.(fails with code spamblacklist)
- Request timeout
- A few parsoid 503s
Some of these can be fixed or can attept retry if the translator know the reason.
A small message on why publishing failed can be helpful compared to dead end "publishing failed" message after time taking translation process.
