F5 Upgrades:

Nature of the work-  Upgrade the F5 chassis systems (two in LC and two in ITF)

The F5 chassis systems host all F5 GTM/DNS and LTM systems in the following way: ITF chassis 1 (ITF primary LTM, ITF GTM/DNS), ITF chassis 2 (ITF secondary LTM); LC chassis 1 (LC primary LTM, LC GTM/DNS). Each chassis will be upgraded, one at time, resulting in the GTM/DNS and LTM systems hosted on the chassis being unavailable for a period of time.

The LTM systems are redundant and services will be moved between the primary and secondary systems as needed. The GTM/DNS systems are redundant and provide the same data. No more than one GTM/DNS and one LTM system will be unavailable at any time.

Expected impact on services-  No service impact is expected.

Which data center-  LC and ITF

Expected impact on services-  None

Expected duration-  2 hours in LC; 2 hours in ITF
