(54004) Global Load Balancer Software Upgrades

Scheduled for Dec 22, 19:00 - 23:00 CST

Scheduled

Northwestern Information Technology will be upgrading the Global Traffic Managers (GTMs), which are used to handle load balancing between services that have presences on both Evanston and Chicago campuses. This is a fully redundant system, and service will continue to run without interruption on one system while the other is upgraded. This maintenance will keep us aligned with the vendor recommended software and will address minor security issues.
No service interruption to applications using the GTMs is expected.

The applications using the GTM are:
