Following an extended monitoring period, our Engineering team has confirmed that the issue has been successfully resolved. The preventive measures implemented have proven to be effective and reliable throughout the monitoring period, and the affected Career Sites continue to operate as expected. To further strengthen the platform and help prevent similar issues in the future, our Engineering team is working on additional backend system and database optimizations. These improvements are scheduled to be deployed as an off-cycle release on 07 Aug 2026. We will now conclude active monitoring and consider this incident resolved. The associated Known Issue (https://cornerstoneondemand.lightning.force.com/lightning/articles/Knowledge/KNOWN-ISSUE-CSX-No-Jobs-Displayed-on-Career-Site-for-US-Swimlanes-Production) will remain in Monitoring status until the scheduled 07 Aug 2026 release has been completed, after which it will be closed. A detailed Root Cause Analysis (RCA) will be published within the next 7–10 business days. Thank you for your patience, understanding, and cooperation throughout this matter!

After careful review and monitoring, we’ve determined this does not meet the definition of a Severity2: emails are firing as expected, and Mailspike’s blacklisting is having only a minor effect on email delivery for customers in the impacted IP—primarily those who rely on Mailspike for inbound email filtering. As a result, the incident is being closed on the Status page, and any further communications will be handled as a Severity3 via the existing Known Issue article: https://cornerstoneondemand.my.site.com/s/articles/Known-Issue-CSX-UK-Email-IP-blacklisted-by-Mailspike CSOD technical teams will continue working closely with Mailspike to address the underlying concerns.

**Issue Summary:** On July 7, 2026, users across all Production regions experienced intermittent service degradation due to elevated background processing activity. The increased workload temporarily affected platform responsiveness and caused delays in certain application workflows. **Root Cause:** The issue was caused by an unexpected surge in background processing requests, which generated a significantly higher workload than anticipated. The elevated processing volume temporarily reduced system throughput, resulting in increased processing times and intermittent service degradation across multiple regions. **Corrective Action:** As an immediate mitigation, non-essential background processing was temporarily restricted to reduce system load and prioritize critical requests. Additional optimization activities were performed to accelerate queue processing and restore normal system performance. These actions stabilized the environment, and processing rates returned to expected levels. **Preventive Measures:** To reduce the risk of recurrence, Cornerstone has updated operational procedures for managing large-scale background processing activities. These updates are intended to better control processing volume and reduce the likelihood that unexpected workload surges will impact Production services.

**Incident Summary:** On June 28th, 2026, at 11:24 AM PT, users in the UK Production environment experienced intermittent service degradation impacting session management functionality. The issue resulted in reduced service availability and intermittent failures while accessing affected applications. **Impact:** Users experienced intermittent service disruption and degraded application responsiveness due to instability within the session management service. Some requests were impacted during the incident window, resulting in temporary failures across affected portal functionalities. **Root Cause Analysis \(RCA\):** The issue was related to transient service instability following infrastructure changes, which impacted the availability and responsiveness of the session management service. During recovery, service initialization delays affected the ability to restore full processing capacity within the expected timeframe, resulting in intermittent service impact. **Resolution:** As an immediate mitigation, service traffic handling was adjusted to allow the affected components to stabilize and recover successfully. Once service capacity was restored and stability was confirmed, normal traffic processing resumed and application performance returned to expected levels. **Preventive Actions:** The following measures have been implemented to reduce the likelihood of recurrence: * Service startup and recovery behavior are being reviewed to improve restoration time during availability events. * Additional monitoring and validation checks are being enhanced to improve visibility into service health and recovery patterns.
