Massive traffic drop due to localized Google SERP changes?

[irock]

I was wondering... I notice a somewhat large drop in traffic for my site, but I didn't notice anything wrong with my USA Google rankings. I was wondering if this has to do with UK, Canada, EU localized Google rankings. B/c for my keywords, I don't rank so well on other markets. Did Google just start to favor local SERPs earlier this week?

I don't usually check with those so I have no idea. Anyone has an idea?

All but 2 pages have vanished from my UK site listings. That may have something to do with the drop in SERPs as two key search arguements normally return pages that have been dropped.
