Set channel permissions

Restrict posting in the incident-response channel to channel admins and on-call engineers for the duration of the major outage. Make the channel readable by all engineering and support staff but prevent reactions-only posts from non-specified roles. After changing permissions, notify the on-call lead and test by sending a test message from a member account.

Before I lock down posting in the incident channel, surface what reviewers care about: who must be able to post, who must be observers, and which integrations need write access. Flag likely hesitation points: blocking automated alerts, cutting out a rotation owner, or failing to notify people after the change. Recommend a short rollback plan and a one-hour observation window.

During the outage I restricted posting to on-call and admins to reduce noise. Now product managers and a monitoring bot complain they can’t post updates. I’m unsure which integrations and roles must remain writable. What’s the likely oversight and the quickest safe fix so essential updates can resume without full reopen?

We repeatedly flip channel permissions during incidents, which causes missed alerts and angry stakeholders afterward. What habit should our incident lead adopt so permission changes are deliberate, documented, and reversible with minimum friction?
