Re: [Wikitech-l] 503 Backend fetch failed
It becomes more and more frequent in the last couple of days. This time I ran into the error in the web browser and got a copyable error message: If you report this error to the Wikimedia System Administrators, please include the details below.

My console ran out, I searched my command log for duplicate command, that's why I think, but I am not sure. Anyway, it was an article of huwiki.

If you could provide the URL or the request that might be helpful. I know for instance that I have sometimes received that error on https://query.wikidata.org/ when there is a query timeout.

Re: [Wikitech-l] 503 Backend fetch failed
503 Backend fetch failed is a generic error message you get when the application server breaks so badly that it fails to even return an error message (e.g. PHP fatal errors can do this), so Varnish has to make up its own error message. ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Re: [Wikitech-l] 503 Backend fetch failed
I’ve seen it a number of times often just redoing the request makes it go away On Tue, Oct 1, 2019 at 9:06 AM Bináris wrote: > Hi folks, > I got this message while running a bot: > Result: 503 Backend fetch failed > > I know HTTP 503 message, but I never got it during botwork.
