Searching from the UK, I am seeing it on both Google.com and Google.co.uk. Interestingly enough, for some queries there are changes on both Google domains and for some queries there are changes on one of the google properties. Ex. for some of the searches, capitalizing the first letter of a search on Google.com yields different results from a non-capitalized search, where it yields the same result in both instances on Google.co.uk.
