The following is the opinion of the author and does not necessarily reflect HEXUS' opinion.
As of December 13th, Sky's block came into action, though, unlike BT who seemed rather upset by the idea of site blocking and who has also been challenging the terms of the Digital Economy Act to protect end-user rights (along with business overheads), Sky has created a webpage defending the decision to block Newzbin2, called Protecting Copyright. It's perhaps one thing to heed court decisions, but it's another to rub salt into the wounds when supporting a legal case that could set a dangerous precedent for site and service blocking in the future.
James Firth of the Open Digital policy organisation has suggested that, unlike BT, Sky likely blocks access to Newzbin2 and other sites using IP addresses. It is well known that the site is frequently changing its IP address and that until the adoption of IPv6, which will supply more addresses for all, IP addresses on the current IPv4 protocol are all but used up and so sharing and recycling of IP addresses is becoming increasingly common place, "Pity the website owner who picks up Newzbin's old IP address," said James.
It is expected that Virgin Media and TalkTalk will also have to comply to blocking access to the site, though neither firm has yet received a court order and TalkTalk, at least, has contested the suggested order, in particular the costs relating to implementation of such a block.
