Vital signs reports a large spike in page views from 9th Nov to 19th Nov (Although it is continuing)
https://vital-signs.wmflabs.org/#projects=wikidatawiki/metrics=Pageviews
To me this spike appears to be consistent with the spike in usage of the query service at query.wikimedia.org.
The spike can be seen on that dashboard http://discovery.wmflabs.org/wdqs/#wdqs_usage
query.wikidata.org should be excluded from the pageview definition / not counted as a wikidata view.
It would also be great if the data could then be regenerated for all historic days possible (if this was in-fact the reason for the spike)
