It looks as though AncestryDNA have just rolled out a new Genetic Communities update which may or may not slightly change your ethnicity estimate. My estimate hasn't changed but it has broken down some of my Scottish heritage into 3 different communities which is cool to see. Quite accurate as far as I know. Has anyone else noticed this yet? Still waiting for the English and Irish genetic communities to show up on my results but no luck as of yet. Even though it is showing ancestry from those areas, It doesn't break it down into the actual locations. It may happen in another update.
