+
+
+**Timestamped incident history**
+
+Every status report, update, and resolution is stored with its timestamp. This is the artifact behind the CC2.3 sample — a durable record you did not have to assemble by hand at audit time.
+
+
+
+
+**Subscriber notification**
+
+Email, RSS, Atom, and JSON feeds. Evidences the proactive half of CC2.3: you pushed information out rather than waiting to be asked. Available from Starter up.
+
+
+
+
+**Maintenance windows**
+
+Scheduled maintenance shows advance communication of planned disruption, which is a distinct point of focus from incident response.
+
+
+
+
+**Audit log**
+
+Every mutation across your workspace is recorded in-transaction, including who or what made the change. Useful for CC7 evidence and for showing your own controls over the status page. Pro and Scale.
+
+
+
+
+## Where openstatus is not the answer
+
+- **Control tracking and evidence collection across your stack.** That is what compliance automation platforms like Vanta and Drata do. Reference your status page from within them as evidence for CC2.3; do not expect one to substitute for the other.
+- **Policies, risk register, vendor reviews, access reviews.** Entirely out of scope.
+- **The inbound half of CC2.3.** Openstatus gives you the outbound channel. You still need a documented, monitored route for customers to report problems to you.
+- **A formal availability SLA report.** You have the underlying uptime record within your retention window; producing a signed periodic SLA report against a contractual commitment is a separate exercise.
+
+## A workable sequence
+
+1. Decide which Trust Services categories you carry. Availability changes what evidence you need.
+2. Write down your incident communication process — severity thresholds, who publishes, how fast. An undocumented process cannot be tested for operating effectiveness.
+3. Make the public record and the internal record agree, every time.
+4. Set retention to cover your full observation window before the window starts, not after.
+5. Keep the inbound channel real and monitored.
+6. Reference the status page as evidence inside whatever platform tracks your control set.
+
+Steps 2, 3, and 5 are the ones auditors actually fail teams on. The tooling is the easy part.
