Hi,
Starting from an unrelated discussion on meta, I noticed a significant drop in main page views for several wikis starting from April this year. Is there anything we (or Google) did at that time to justify this drop?

hu.wiki: http://tools.wmflabs.org/pageviews/?project=hu.wikipedia.org&platform=al...
fr.wiki: http://tools.wmflabs.org/pageviews/?project=fr.wikipedia.org&platform=al...
de.wiki: http://tools.wmflabs.org/pageviews/?project=de.wikipedia.org&platform=al...
en.wiki: http://tools.wmflabs.org/pageviews/?project=en.wikipedia.org&platform=al... (slightly different pattern)
The same cannot be said for other projects, for instance uk.wiki: http://tools.wmflabs.org/pageviews/?project=uk.wikipedia.org&platform=al...
Thanks, Strainu
