Thanks for the link. That is specifically about LibGen and Anna's Archive, and links to the general agreement that when a court orders one ISP to block a pirate site, others will also block it. I suppose in situations where Sci-Hub forwards you to LibGen (does it still do that?) that means you'll be blocked regardless of the blocking status of Sci-Hub itself.
I am still unable to find any news about court orders relating to Sci-Hub in particular. The biggest ISPs appear to not publish their block lists unfortunately. I did find that Delta publishes their list[1] of blocked sites which includes only sites for which I can also find news about court orders, and does not include Sci-Hub.
I queried the KPN DNS servers and they return a KPN IP address for LibGen, but a DDOS-Guard IP address for Sci-Hub, so that leads me to believe KPN doesn't block them either at least.
