I too see a block (Belgium) but due to the Brussels business court. That said, your message is funny and completely false, it seems Vodafone. ziggo needs to update their lawyers.
The council of Europe is a human rights body based in Strasbourg, broader than the EU. It is a kind of democracy watchdog and has no sanctions or telecoms authority.
There is the European council, which is the EU body composed of the 27 heads of government, which indeed has sanctioned Russia today by withdrawing it's broadcasting license (X) but I cannot find any source that says that says that telecoms have to block it's content.
And of course this all is not Russia today, but maybe they use some of the same servers, which might explain the question raised here how Anna's Archive keeps the lights on.
