(I'm from The Netherlands)

For what it's worth, XS4ALL has a tremendous reputation when it comes to privacy in The Netherlands, being one of the first ISPs in NL, founded by true hackers. They were the first (and only one?) that started disclosing how many subpoenas they were receiving from the government, have fought a lot against blocking TPB in court, etc -- I'm not surprised at all they are the ones hosting the Tor servers (I am a customer, and am allowed to run an Exit node, and they are very supportive when they receive abuse complaints, their entire customer support staff knows about Tor). I would be surprised if they would easily cave to a government order / seizure of their servers.
