It also seems that our long tail keywords have bombed as well.
It would make sense that long tail would provide a significant portion of the "not provided" keyword.
We have a .co.uk domain and the site is hosted in the UK so I don't think your suggestion would really hit us. 82% of our traffic is from the UK.
I think this is all about the long tail and we have been hit for some reason...
