Last week, we posted several updates from the Google Analytics team regarding the issue they are having with April 2011 data when applying advanced segments, secondary dimensions, or custom reports.
On Friday evening, they posted the following update:
Update 5/13/11 3:45 PM PST
April data affected by this issue has been restored for all days after and including April 20th.
Based on our review of some Google Analytics accounts, it looks like at this point they have restored data from April 9th forward. However, there has been no official update from the GA team yet.
We will continue to keep everyone posted on any updates from the GA team.
