Sorry, I know HN isn’t a support forum, but am I the only one who gets “Safari couldn’t establish a secure connection” to any of the archive.xx sites? It’s been happening for ages now.
It must be something in my network path because I just tethered to my phone's 4G connection and it works. Odd.
In short if you use Cloudflare's 1.1.1.1 DNS then some archive.is domains won't load so you should perhaps use another DNS server.
Edit: Not because 1.1.1.1 is in the wrong it is just what the person behind archive.is recommends as he will not be changing his position and neither will Cloudflare so it's a bit of a stalemate.
