Our series of sites is also suffering from this problem. I have to put in a vote of agreement for the fact that Google seem to be targeting this at very retail heavy areas.
My site and top few competitors have dropped out for our 2, 3, 4th keywords say "red widget" "blue widget" and "widget sale" however our main keyword "best widgets" dropped off and returned next day. The number 1 keyword is in our URL but I don't think this is related.
I also investigated datacentres and have found 9 times out of 10 we are out of them all. Every now and again however we will hold our position in the "search in the uk" results (we are a UK based company).
I am going to give it time before I try to make changes, I don't want to aggrivate the problem.
