Priority High
Affected Services VDI & DaaS Web Console
RCA Reference 03/07/2026
Executive Summary OnJul 3, 2026, customers using the VDI & DaaS Web Console experienced a temporary loss of visibility into real-time and historical monitoring data. The issue was caused by an unexpected service interruption in the Monitor Proxy layer following automated operating system security updates on production servers. Customer data was not lost; the incident affected data visibility only. The engineering team restored service by redeploying the affected Monitor Proxy services, and customers were able to see their data again shortly after recovery. To reduce the risk of recurrence, automatic unattended OS package upgrades have been disabled on the production Monitor Proxy servers, related hardening automation has been updated, and additional resiliency improvements are being evaluated.
