After moving from e52153e to rMW1e54f0c5f416 and running update.php (the latter probably unrelated), piramido.wmflabs.org consistently fails to load pages with an ApiRunJobs error:

[c71ea2c8] /wiki/Special:Random Exception from line 1366 of /srv/mediawiki/includes/api/ApiBase.php: Invalid or stale signature provided

Backtrace:

#0 /srv/mediawiki/includes/api/ApiRunJobs.php(54): ApiBase->dieUsage(string, string, integer)
#1 /srv/mediawiki/includes/api/ApiMain.php(862): ApiRunJobs->execute()

#5 /srv/mediawiki/includes/Wiki.php(451): MediaWiki->triggerJobs()
#6 /srv/mediawiki/index.php(49): MediaWiki->run()
#7 {main}

It looks like the socket method is failing, probably for the same reason a simple:

curl 'http://piramido.wmflabs.org/w/api.php'

fails on piramido with:

curl: (7) couldn't connect to host

I think Labs currently can't connect to itself with external host names.

There is a fallback that should work, but it's throwing the above exception consistently.
