Web rot is a well-known problem and I frequently come across old blogs with lots of broken links. I want to prevent this from happening to my blog so I'm considering different options of archiving the pages that I link to. The archive.org is big and likely won't go away very soon, but it's also quite slow. Archive.today is faster, but I'm skeptical of its reliability. It's also been around for a while, but there is little information on its funding on its website. How reliable are these sites and what model of funding (private, university, non-profit) is likely to best support saving pages for the long term?

My preferred option at this point is to not depend on any outside archive at all and instead upload snapshots of the pages I link to on my own page. That way, the content of the page I was linking to is surely available for as long as my blog stays alive.
