Oh absolutely. So many dead links scattered around the net. It's gotten so bad an independent group Archive Team are brute forcing URL shortners so these links aren't lost to time. Just look at how long the list of dead shorteners is https://wiki.archiveteam.org/index.php/URLTeam#Dead_or_Broke...

72,287,136,510 links scanned, 14,632,045,317 shortened URLs archived. If you are interested it's easy to run their docker image to help with this and other archival projects.
