I’ve been using archive.ph since I set up autotext for it on my device. You can view archives of a page, or request a page to be archived, by opening https://archive.ph/<url>—eg, https://archive.ph/https://news.ycombinator.com/).
I have found archive.ph to be great. Pages I try to open—normally HN and memeorandum.com posts from paywalled sites—are almost always already archived, and if not requesting a new archive works well in a reasonable amount of time.
I know that there are many other similar web archives, and I’m sure folks here have opinions about them. Do you have a preference? Why?
Most importantly, when folks post archive links for HN posts, which archive(s) would you prefer people to use?
