I've been away at a job with an employer that is in the middle of a crisis. The crisis has been getting worse and frankly I have not been keeping on top of much of anything. When alternative download formats for podcasts were being rolled out, Archive.org was used for storage. Essentially that acts as our backup. Since the iTunes Music Store has dropped the podcast listing for the time being, users looking for old episodes can visit Archive.org to find more.
As to rebooting the podcast(s), we need to take things one step at a time. I need to ride out the crisis with my current employer as it is. Whether or not my current employer survives the crisis is thankfully not up to me.
