Cloudflare's malware protection resolver (1.1.1.2) now blocks archive.today as a Botnet C&C: https://news.ycombinator.com/item?id=47474255
This is absolutely warranted, seeing that archive.today abused its customers for a ddos attack against a blog that the (anonymous) owner disliked.
It's also a welcome help for media companies worldwide for whom archive.today is a thorn in their side, bypassing paywalls and other content gates.
IMO: This shows - again - the dilemma of filtering resolvers.
