Create an outage announcement channel for major system downtime

Create an org-wide announcement channel for major outages so all affected users can be notified immediately when a critical system is unavailable.

Transcript Context

The discussion referenced a prolonged Attik outage where only part of the organization was notified, which left inspectors trying to complete jobs and other teams unaware of what was happening. The preferred workflow was a single Google Chat announcement channel for all Attik users rather than relying on leadership relays or ad hoc text chains.

The channel should be used only for major outages that materially affect customer communication or internal operations. The discussion explicitly called out Attik and Dialpad-style outages as examples. The goal is to let anyone working know the system is down without requiring a manager to figure out who is on shift and pass the message along manually.
