We have hundreds of sites being tracked with Google Analytics – every single one of them had 0 traffic (or visitors) on Thursday, May 6th, 2010.
Did analytics break or was there just an error?
It looks like there was a severe drop in internet activity (if you only look Analytics data).
But as business contingency would have it.. when we check the server statistics for visitors, it shows there were actually people on our sites clicking around!
With that data, we can be sure that it was a Google Analytics error or broken database connection.
If your GA traffic shows zero (0) on Thursday, May 6th, 2010, don’t sweat it.. there was traffic to your site – it’s just that GA wasn’t working.
