Same here in the UK. Looks like before my ISP had blocked the specific IPs AND the domain at the DNS level. Obviously now TPB is using a different IP, so if you use Google's DNS servers instead of your ISP's then you should be able to access the site just fine.
Same here! It was banned in Argentina and now I can access to it without problem. My guess is that they are using a new IP (pinging thepiratebay.se gives me the IP 104.28.5.42, which seems to be part of CloudFare network). I'm reading the legal order (http://www.scribd.com/doc/232031432/cnc-tpb-argentina-pdf) and they not only ask to ban IPs from 194.71.107.0 to 194.1.107.255, they also ask ISP DNS resolvers to ban thepiratebay.se (an related domains). Good thing I'm not using my ISP DNS :)
