If you are among those people with missing data for February 9, 2015 in Google Analytics, the data has now been restored.

It is unclear what made the information vanish for a week, although people were suspecting it might have had something to the corrupted database. Many people were seeing the data from the 9^th the following day, until it disappeared on the 11^th.

Google reported on the 13^th that it was a “bad case of the Mondays” and that the data should be showing back up within the day.

We’re sorry for our unusually bad case of the Mondays. We’ve fixed the issue and no data was lost. Analytics users should start seeing any missed soon.. Please find more information on our status dashboard

However, there seemed to be some problems the Google Analytics was having restoring the data within this time frame. It wasn’t actually until Sunday the 14^th that the data was completely restored all users.  The seemingly related outage affecting search query data in Google Webmaster Tools was also fixed.

So if you are waiting to do your weekly reporting for the data say that, and you have the all clear to go ahead.
