What the ephemerality of the Web means for your hyperlinks
Of these deep links, 25 percent of all links were completely inaccessible. Linkrot became more common over time: 6 percent of links from 2018 had rotted, as compared to 43 percent of links from 2008 and 72 percent of links from 1998.
Nothing is permanent on the Internet, which causes me to wonder if that conditions one to also have a loose view about facts and truth.
