I just left a comment on this elsewhere, but are you using cloudflare or nextdns? They seem to block archive sites, especially archive.today (archive.is, etc)
The NextDNS (and others) blocking of archive.today goes back far beyond 2026 and this specific DDOS event. Perhaps that contributed to the hostility behind it, I don't know. But citing that event for other examples does not apply well.
Please do not misinterpret this as an excuse or pardon of anything. I love archive.today and all their subdomains. I use it regularly and have been having problems for years, especially with NextDNS. I am seriously disappointed to learn of the DDOS event, but there remain other angles on the topic in general. I am still struggling to process WTF they would do what you reported -- how could they think that would be worth the consequences, accomplish anything? Almost seems suspicious in itself.
Thanks for the info. But ever a shill for archive.is
You should immediately switch your internet provider to Andrews & Arnold https://aa.net.uk/ - every HN reader from the UK should. I'm certain they won't censor you any more than required by law.
