In December 2021, the CEL site suffered an unrecoverable issue when the hosting server shut down. I will not recommend ever using IBMHost, but I should have done a better job with backups. Without recent backups, I was unable to move the site to a new server.
But CEL is now in a rebuild phase. There is a lot of framework that needs to be done. And then a lot of research to bring back all the information that the CEL site was known for.
