WWW is usually just a CNAME in your dns zone file that points to domain.com. So it's not a subdomain in the physically hosted sense although it most certainly can be hence google's confusion.

Servers are cheaper in the USA and the speed difference is hardly noticeable if at all. I'd rather have a faster server in the US for the same price as slow server in the UK (bandwidth costs more in the UK).
