alt Hacker NewsArchive.today (and all of its mirrors) have been unusable for me over the last week or so.
Prior to that it was incredibly unreliable; but I've only had success using it once (trying all mirrors) in the last couple of weeks.
Does anyone have recommendations for alternatives?
I don't have a direct answer but I hope this will help anyway.
I have found that https://archive.today/, https://archive.is/ and https://archive.ph/ don't resolve correctly when using quad9 or cloudflare dns servers. To work around that I use other dns servers for their name resolution. Maybe you're experiencing a similar issue?
