Same from Canada. Also, would seizing the domain name actually stop the clients from working? I would imagine that the devs, seeing the rash of increasingly ridiculous seizures, would have pushed an update to the client that bypasses DNS. That's what I would have done, anyway.
ub.com and pokerstars.com both resolve to their original servers (77.87.179.116 & 66.212.231.205) using either Google's DNS servers (8.8.8.8) or Level3's (4.2.2.1, 4.2.2.2)
