Nature of the work – The F5 chassis, LTMs, and GTMs will be updated to the current release of software at both ITF and LC datacenters.

Expected impact on services: Due to an ongoing degradation of service with the F5 GTMs and the campus DNS service, the required reboots for the GTM in LC will cause two brief 5–10-minute outages for services that are fronted by the GTMs. Some of the high impact services include:

ADFS (primarily impacting Microsoft 365 logins)

dc.iowa.uiowa.edu

gc.iowa.uiowa.edu

Data Center Proxy Services

If you have questions about the impact to your GTM-based services, please reach out to your EI Systems Administrator for more information.
