Kubernetes has announced on GitHub that the community will lose its privileged Slack access and that it will be reverted to a standard free account – on Friday, June 20, 2025.
The discussion post points out the consequences for users, especially channel owners and user group participants. Until Friday:
- Users will no longer be able to access pinned posts or files that are older than ninety days. The authors recommend backing up the data elsewhere, for example on GitHub or Google Docs.
- The same applies to posts in private channels: Kubernetes can no longer back them up. Slack admins are reportedly looking for a tool to help, and those affected should contact #slack-admins.
In the following weeks:
- User Groups will stop working despite membership. Anyone who needs a new Slack channel as a result should fill out an issue.
- Important data in private messages should also be backed up, as they will be lost.

Unprivileged, free Slack access has numerous limitations. There is only a ninety-day history, no user groups, no workflows, only ten apps and no customer service.
The Kubernetes team and the CNCF members there are considering switching to Discord. The editorial team does not yet have any information about the background to the change. Kubernetes and Slack have been asked to comment
