Hmm, for the last 4 days my UV's have been exactly the same number. Coincidence?

Did your traffic from Google keep increasing until it bumped up against a limit over the last four days?

If this is the highest level it's ever reached, then throttling could have kicked in to prevent it from going higher. But if it has previously been higher in the past, then it probably isn't being throttled now.
