 For shorter-lived discussions, our community chat open to all on both Slack and Discord:
 
-* [Slack](https://filecoinproject.slack.com)
+* [Slack](https://filecoin.io/slack/)
 * [Discord](https://discord.com/invite/filecoin)
 
 For long-lived discussions and for support, please use the [discussion tab on GitHub](https://github.com/filecoin-project/community#forums) instead of Slack. It’s easy for complex discussions to get lost in a sea of new messages on those chat platforms, and posting longer discussions and support requests on the forums helps future visitors, too.
