UEN Router Software Upgrade 5/29/15 5-7am, Service Disruption Possible

On Friday 5/29/15, during the 5-7am maintenance window, a software upgrade will be performed on multiple University Enterprise Network (UEN) routers. During this upgrade, UEN connectivity will be disrupted for approximately 3 minutes for customers without redundant connections who receive backbone connectivity from these UEN routers:

Pollock3
Computer3
Pattee4
Telecom7

Customers with backbone connectivity to the above routers who have redundant UEN connections will be degraded as connectivity fails over to the redundant connection and as connectivity fails back to the primary connection.

The purpose of the software upgrade is to address known issues with line cards that has created packet loss after extended run time in some UEN routers.
