.com is NOT visible in the UK 'sites in UK' search
this happened last year to a load of .coms and .nets even where they were hosted in the UK. Google finally admitted it was a geo-targeting bug, but I never managed to identify what caused it. Sites with mainly US directory IBLs were fine, sites with nothing but UK hosted non-directory IBLs were hit.
