They probably are, but that doesn't mean W3C is the source of your

OK, that is usually important.

No. Various organisations offer location lookup services. While these may  
be based on IP address, or use IP address, there are various other things  
they may take into account. A common one is to keep a database of wifi  
routers, on the (not very good) assumption that these don't move much.

If Google is getting it wrong, it seems reasonable to assume their  
location lookup service is doing something wrong - and it may be that  
others who get it wrong are relying on Google for that service (which in  
turn my rely on a 3rd party). I am afraid I don't know how you tell Google  
they made a mistake, but I am sure you can find that information somewhere.
