Yes, I m facing the same thing and I think it is since yesterday... i got very few impressions yesterday also..
The stats are beginning to be updated now. Mine are still a lot lower than usual but at least they have finally changed from what they were this morning
Oh wow *breathes sigh of relief*. I got about 13000 impressions for the day so far on my site, but google had stuck at 2000 and I only earned 3 cents. It is still stuck to this moment.
