If that's Parsoid trying to hit Varnish, see T102178

You can reproduce that error easily (without manually editing the VE error handling code live on silver) by browsing to http://parsoid-lb.eqiad.wikimedia.org/labswiki/Main_Page

This looks like a Parsoid <-> wikitech API communication issue to me. Moving on to Parsoid.

Might be due to lib/mediawiki.ParsoidConfig.js's check for private/fishbowl wikis, which would turn off use of the default proxy. But since https://gerrit.wikimedia.org/r/#/c/218903/ wikitech has not been marked as a fishbowl (because it's not one)

Krenair added a comment.EditedAug 12 2015, 4:12 AM

https://gerrit.wikimedia.org/r/#/c/228024/1/lib/sitematrix.json - seems like Parsoid has it's own local version of sitematrix and wikitech was updated to no longer be a fishbowl as of 2015-07-30 (which would explain why we only just noticed this while the original operations/mediawiki-config change was on 2015-06-17)

Yes, we have a script that Arlo periodically runs to update the local cached sitematrix entries.

Should the sitematrix mark it as nonglobal?
