EasyDNS has a chilling post on VeriSign taking down a Canadian Web site in order to service a warrant from the state of Maryland:

We all know that with some US-based Registrars (cough Godaddy cough), all it takes is a badge out of a box of crackerjacks and you have the authority to fax in a takedown request which has a good shot at being honoured. We also know that some non-US registrars, it takes a lot more “due process-iness” to get a domain taken down.

But now, none of that matters, because in this case the State of Maryland simply issued a warrant to .com operator Verisign, (who is headquartered in California) who then duly updated the rootzone for .com with two new NS records for bodog.com which now redirect the domain to the takedown page.

The implications are chilling. So now if you use a TLD that is under the control of a US company, your Web site is in US jurisdiction.
