Wikimedia Report Card December 2009


Erratum 1: Section PAGE REQUESTS

Server overload caused underreporting of page requests

The problem started in December 2009 and was only detected in July 2010
At that time data for April 2010 - July 2010 could still be corrected from available logs.

From Report Card July 2010 onwards underreported months December 2009 - March 2010 have been marked in the chart (greyed zone). Underreporting was an estimated 10%-25%.
