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.

Reporting 2.0 – FRA (EU) SL1 - Unable to Create or Edit Reports Due to Unresponsive Report Builder
Resolved - The Engineering Team has confirmed that Reporting 2.0 is now functioning as expected. This is successfully resolved.

Thank you for your patience and understanding!
Oct 12, 02:13 PDT
Investigating - Users may experience an issue with Reporting 2.0 in the Production environment, where the report builder fails to load the available data fields, preventing users from creating new reports or modifying existing ones.

When users attempt to create a new report or edit an existing report, the report builder interface loads but does not display the available fields required to configure the report. As a result, users are unable to add or modify table columns, apply filters, or complete report configuration.
