 ## Public Instance
 
-We're currently working hard on cutting a 1.0 release and productionizing the public instance.
-We don't have a date yet, but follow along on the [GitHub project](https://github.com/orgs/sigstore/projects/5).
+Rekor is officially Generally Available with a 1.0.0 release, and follows [semver rules](https://semver.org/) for API stability.
+This means production workloads can rely on the Rekor public instance, which has a 24/7 oncall rotation supporting it and offers a 99.5% availability SLO for the following API endpoints:
+* `/api/v1/log`
+* `/api/v1/log/publicKey`
+* `/api/v1/log/proof`
+* `/api/v1/log/entries`
+* `/api/v1/log/entries/retrieve`
 
-We will improve the stability and publish SLOs soon!
+For uptime data on the Rekor public instance, see [https://status.sigstore.dev](https://status.sigstore.dev).
