A Huffington Post story details the effects of DMCA notice served on Hurricane Electric by the US Chamber of Commerce to take down a spoof site by the Yes-men – the site suggests that the Chamber has done a u-turn on its controversial position vis-vis climate change. What is notable is that, rather than being the actual host ( May 1/People Link), Hurricane Electric is the upstream provider. In acceding to the request it disconnected every single site on the host. The situation was soon resolved – and the site moved to a mirror – but the incident has given rise to some discussion, not just over the legitimacy of the DMCA claim, but of the responsibilities of network operators in such circumstances. On the latter find below some excerpts from a related NANOG thread.
