- cl-difflib and cl-html-diff: host lemonodor.com has stopped working. update David pointed out in the comments that these projects are available in github.
- coretest: project owner on github (trialcodr) is deleted
- fcgi: host tehran.lain.pl has stopped working
- genhash: host src.hexapodia.net has stopped working
In the Quicklisp universe there are almost no dependencies on these projects, but that might not be the case in the wider world of CL applications. Do you use any of these libraries? Are you interested in keeping them alive and running in some upstream form?
