Where did the old web go? We followed 657,607 links to find out

The post comes from the creator of 0.mk, a URL shortener that ran from 2009 to 2014 and was recently restored from an old database backup. Using that recovered corpus, the author crawled 657,607 historical links and found that roughly three quarters no longer return a loading page. Even after removing duplicate destinations, the failure rate stayed almost the same, so this was not a quirk of a few heavily reused URLs. The author is careful about the wording. "Did not load" includes hard failures and also pages that may now block crawlers, while links that still return 2xx or 3xx count as live even if they now point to parked domains, login walls, or removed content. The result is not a clean census of the whole internet because the service was concentrated in one regional community, but it still lands as a stark sample of how quickly shared web history disappears.
Treat any external URL you depend on as fragile infrastructure. If a link matters to your product, docs, research, or compliance trail, archive it, snapshot it, or store the content you are allowed to keep instead of assuming the web will stay put.
