Description Michelle Grover 2013-08-26 05:15:22 UTC 
I'm trying to make sure that our latest code is out on beta labs by checking the Special Version Page but I'm getting an error.
Comment 1 Antoine "hashar" Musso (WMF) 2013-08-26 07:47:25 UTC 
Special:Version would try to get the HEAD commit date for each of the extensions which takes roughly 34 seconds.  There is most probably a lower timeout on varnish side which prevents it from successfully retrieving the page :(
Comment 2 Antoine "hashar" Musso (WMF) 2013-08-29 19:53:56 UTC 
Moving this bug to MediaWiki > Special Pages, it needs some cache or something.
Comment 3 Andre Klapper 2013-09-02 12:18:05 UTC 
Confirming:

Comment 4 MZMcBride 2013-10-12 22:36:42 UTC 
It loads intermittently.
Comment 5 Bartosz Dziewoński 2013-11-16 01:23:48 UTC 
Come on guys, what we have here is practically a DoS vector. Can somebody do something about it?
Comment 6 MZMcBride 2013-11-16 17:51:37 UTC 
This is related to some MediaWiki configuration variable, isn't it? Which one, exactly?
Comment 7 Gerrit Notification Bot 2013-11-17 17:46:25 UTC

Patch still awaiting review...
Comment 9 Nemo 2014-01-29 18:33:19 UTC 
I thought the dates were removed, but it must be some configuration only: still relevant.
