Well I think the network is good in EU so it does not matter if you host your site in Germany, Spain, Netherlands or UK. Of course support, language and common marketplace are extremely important. You know that there are many people who prefer to communicate in their own language but not in english. So they will choose a provider from their own country. At the same time you can not have customer support in 25 or more EU languages. The Commission in Brussels could affor it

but not small businesses.
I like the way people in UK do business and that's why I'm saying that only UK companies are capable enough to provide quality service accross Europe at this time.
