InterQual Firewall System Maintenance – Action Required
Scheduled Maintenance
Report for Optum Solutions
Completed
The scheduled maintenance has been completed.
In progress
Scheduled maintenance is currently in progress. We will provide updates as necessary.
Scheduled
This communication is intended for InterQual® Cloud Solutions customers.
Optum will be performing system maintenance to further improve InterQual’s security posture by implementing the Cloudflare web application firewall (WAF) in the InterQual Cloud Solutions production environment May 2, 2025, 11:00 p.m. ET. The production environment will be unavailable for approximately one to two hours while this maintenance is underway.
Action Required
No action is required for most customers.
After maintenance is completed, InterQual Cloud solutions will use a new range of rotating IP addresses for incoming traffic. If your organization has configured allow list rules based on InterQual IP addresses instead of URLs, you will need to add Cloudflare’s IP addresses to your allow list: https://www.cloudflare.com/ips/. IP addresses for outbound traffic from InterQual Cloud solutions are not impacted by this change.
The Cloudflare WAF has been in place in the InterQual Cloud Solutions test environment since Sept. 30, 2024. If you have not tested connectivity with the test environment since then, we encourage you to do so as soon as possible to identify any potential issues before these changes are implemented in the production environment May 2, 2025. If you experience any issues with connectivity in the test environment, please contact Product Support.
