About This Site

Welcome to Cornerstone System Status Dashboard!

This page shows the system status for the Cornerstone SaaS environments.
Downtime is when a swimlane is not accessible by 25% or more of our customers by any login method and the incident resides with Cornerstone (rather than the customer's connection). This excludes any planned maintenance , patch or release (please see calendar linked to the bottom left of this page)

The current status column is updated in near-real time to reflect any ongoing production issues.
You can Subscribe to updates via Email/SMS and Web hook by clicking the "Subscribe to updates" option just below the Cornerstone Banner.
