Root Cause Analysis

This incident was caused by an outage with our CDN provider that disrupted connectivity between their network and our Support dashboard servers, resulting in errors and blank pages or login failures for affected agents.

Resolution

To resolve the issue, we coordinated with our CDN provider and initiated a temporary traffic reroute to reduce errors while the provider addressed the incident. Once stability was confirmed, traffic was switched back to the normal route, and the alternative path was secured.

Remediation Items

Investigate why the system did not trigger a failover alert during the Chicago Cloudflare outage to improve future detection and response.
