Here is one older article about it. It appears to only cover the larger ISPs — https://torrentfreak.com/dutch-court-orders-isp-to-block-ann...
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.
