When you visit a site, you should use the webarchive's tooling to save a snapshot of the page incase for whatever reason, the page goes down in the future.
For example, the other day, I was working on the configuration of my emacs installation, and a great resource is tecosaur's doom emacs configuration, and as such, I made sure that I have a backup of it here: https://web.archive.org/web/20250304194331/https://tecosaur.github.io/emacs-config/
All you have to do is head on over to web.archive.org, and at the bottom of the page is a "Save Page Now" link.
Copy-paste the url into that box, and use that version for all of your future linkings to it (that's not a word.)
You will probably not have to do this for every page, but it is good practice. In the nearly 3 decades I have been online, I only wish I had know this sooner and used it for things that I found interesting. This also helps to preserve the web for posterity's sake. Win-win.
As always, God bless, and until next time.
