Around 3 years ago I revamped planet.gnu.org and hosted it myself, as the previous host was defunc.

I won't have the energy host it for much longer, so planet.gnu.org is now looking for a new host and maintainer.
In any case I'll shut down the service when I upgrade to Debian 11 "bullseye" in a few months.

Everything needed to run the service is documented and stored in the infra and config repositories, there is no private data. A previous blog post discusses upcoming tasks. The planet@gnu.org contact point is now managed by GNU's Mailman instance. The DNS alias is managed by the FSF sysadmins.
