Talking of my site .. the urls that are still there in the index are mostly deep urls which are probably least crawled.
Any one else noticing this?
I am experiencing the exactly same. I use a.uk.com hosted in a UK datacenter and have ranked well within the UK for years this weekend has seen me dissappear from the uk serps.
There is a well known ladies cosmetics brand (**** calling) in the UK who advertise on the TV. They use the extentsion .uk.com and are suffering exactly the same.
