The web has nothing built-in for archiving and versioning. It's a gaping hole in this technological platform, one that has been noted and criticized for a very long time. The reality of this problem, however, is vehemently denied by the current generation of "technologists". Of course, those are the same people who get six-digit salaries for managing complexity they themselves create - partly through hyper-centralization. Good and resilient archival, on the other hand, necessarily implies some level of decentralization.

I singlehandedly maintain a 14-year-old website that used to be a modestly popular web magazine. It's not very expensive, but it's a pain. DNS system is horrible and it's easy to loose domain names to some nonsense. (I lost one that used to be a free 2nd level domain when it was converted to a paid-for zone. Not a matter of money, just paperwork.) Server management is a time drain. Stuff like adding SSL certificate to a legacy VPS can lead to a cascade of updates and config changes that can take days to make and test.

BTW, everyone sings praises to archive.org (and it's well-deserved), but most people here do not seem to realize that they are also a centralized platform that can collapse and take everything down with them. Who archives the archives, etc. Fortunately, they are not the only one of the sort. Unfortunately, it's all very ad-hoc.

If W3C weren't a bunch of corporate shills, there would be a standard for creating versioned web archives, like, 10 years ago. It's obvious that we need one.
