As we have been reporting over the past few days, Google Analytics has reported issues with April 2011 data when applying advanced segments, secondary dimensions, or custom reports.
Yesterday, the GA team released the following statement:
Update 5/11/11 10:30 AM PST
We want to reiterate that no data was lost due to this issue, and we’re working hard to make the April data fully available in your Analytics reports. Our current timeline for restoring full functionality for April data is approximately 12 days, May 23rd. We’re doing what we can to shorten this period. We’re restoring the data day by day so you will see it come in to your account over time and not all at once. Keep in mind, that you can view the affected April data through the standard reports.
We’ll continue to keep everyone posted on any new updates from the Google Analytics team.
