Changes to Wikidata are currently propagated to the Wikipedias with a lag of several hours, but this should be fixed during the next few hours.
The Dispatcher, who is responsible to push the edits from Wikidata to the individual Wikipedias, choked yesterday on some edit. We did not notice until the morning (thanks to the community for reporting on various places). We got the Dispatcher running again. The backlog then was about 19 hours, and is now going down again, it seems roughly at a rate of two hours per one hour, so it should have caught up in about half a day. You can see the [[Special:DispatchStats|current status on wiki]].
We currently do not know why the Dispatcher got stalled, and also not on which edit exactly. We simply skipped a few edits, and it started working again. We will continue investigating. Because of that, it might happen again any time. We keep watching the stats. A detailed description of our current status can be found on the [ http://article.gmane.org/gmane.org.wikimedia.wikidata.technical/117Wikidata-... mailing list]. --[[User:Denny|Denny]] ([[User talk:Denny|talk]]) 11:32, 13 July 2013 (UTC)
