Really?

Then your experience differs greatly from mine (EU based). My usual mix of 'fastest anycast' upstreams’ are reliably black-holing a lot of .ru domains right now

(Rightly or wrongly is a ‘nother question for a ‘nother day).

P.S, YMMV and obviously does :)

Are you sure it's not Runet dropping traffic incoming?

Could you give a couple of examples of the black holing you've seen?

In slovenia, at least these two are blocked at the DNS level:

https://www.rt.com/

https://sputniknews.com/

Interestingly enough, the 'academic network' (arnes) that covers schools etc., and also some government entities is not blocking it, but atleast two out of the three largest commercial ISP are (can't test the third, since it's locked to their customers' IPs only).

Because the russian media mafia (tacc, rt, sputnik and the like, which are all either directly state-owned or via the state-owned tv novosti) are about to be banned in all EU countries where they are still available, and the ISPs might have banned them pro-actively.
