Hello, in Arabic wikipedia, many users report technical difficulties when they try to access the main page. some user have reported a very long delay (about 1-2 minutes) before they can load the main page. I was suspecting a server name indication since the secure server produced an error about the main page was not exit! They experience the same issue after purge/bypass main page,s cache. The errors occur per requesting the main page within the mediawiki interface using the main page's link, or by typing the address directly. Here is some error they have reported: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /wikipedia/ar/wiki/الصÙØØ©_الرئيسية. Reason: Error reading from remote server Apache/2.2.14 (Ubuntu) Server at secure.wikimedia.org Port 443 ----------- A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: https://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script Query: UPDATE `user` SET user_touched = '20120911172013' WHERE user_id = '138585' AND (user_touched < '20120911172013') Function: User::invalidateCache while other pages can be modify/read naturally, a request to the main page made by a user who saved the main page,s path in his bookmark produce this error: Request: GET http://ar.wikipedia.org/wiki/%D8%A7%D9%84%D8%B5%D9%81%D8%AD%D8%A9_%D8%A7%D9%84%D8%B1%D8%A6%D9%8A%D8%B3%D9%8A%D8%A9, from 62.76.41.63 via cp1004.eqiad.wmnet (squid/2.7.STABLE9) to 10.64.0.130 (10.64.0.130) Error: ERR_READ_TIMEOUT, errno [No Error] at Fri, 14 Sep 2012 10:58:32 GMT I,d like some one to investigate the issue and give me a recommendation and feedback, best regards.
Plus certain long pages can't be edited unless user has logged off, e.g. http://ar.wikipedia.org/wiki/اليمن

Antime / Zack: Is this still a problem for the main page? Loading time here was acceptable (less than 8 seconds) with a clean browser cache. I also tried the Yemen article on https://ar.wikipedia.org/wiki/%D8%A7%D9%84%D9%8A%D9%85%D9%86?forceprofile=true three times, and the 3.8MB for that article taking always between 27 and 29 seconds in Firefox 30 with the "Network" tab of the "Developer tools" (but please do note that ?forceprofile=true makes it way slower!).
