10 expired domains with Columbia University backlinks, verified against the Common Crawl web graph. Age, history and availability checked. Browse free.
This page lists 10 expired domains with Columbia University backlinks. Each has expired, is available to register, and has at least one referring domain from Columbia University that survived the original site going offline. Names are masked until you reveal them. Every metric is open.
The Columbia University link is found, not claimed. Referring domains are counted from the Common Crawl web graph, a public crawl of the web, not from a paid link index. Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing that turns out to be registered is removed. History comes from the Internet Archive: the Wayback Machine snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and archive history into one 0 to 100 grade, computed across the whole directory.
A link from Columbia University is one signal. Read it alongside the referring domain band, the archive history and the Revised Score on each listing, and browse the other sources for domains linked by universities, encyclopedias, communities and press.

The link was found in the Common Crawl web graph, a public crawl of the web, pointing from a Columbia University page at the listed domain. The graph is a snapshot of the crawl at the time it was built, so a link removed since then can still appear until the next snapshot is processed.
It depends on what you build. The link stays in place as long as the Columbia University page does, and it resolves to whatever is at the domain now. Google's site reputation abuse policy targets expired domains repurposed for unrelated content, so a site that continues the old domain's subject keeps the benefit and one that changes subject should not expect to.
