IRIS is upgrading all edge network switches in Cory, Soda, & BWRC. The new switches will provide gigabit Ethernet to all wired network connections.

During the upgrade, most devices will experience only one or two brief disruptions of a few seconds each as cables are moved during the scheduled maintenance window.

There is a possibility that physical constraints will force extended downtime in some areas; we will contact sysadmins of registered systems in advance.

The upgrade will take many weeks and this schedule will evolve and change. Please revisit this announcement to find the current schedule.
