This Sunday during our established maintenance window between 6 and 10 am we will be performing maintenance on several systems that will result in service interruptions.

Between 6 and 7 am there may be 2-4 short (less than 1 minute) Internet connectivity interruptions as enhancements are made to the operations of our border gateway routers and we dual home network switches in the path between our network core and upstream Internet service providers to provide additional redundancy.

We will be relocating one of the network appliances that establish the VPN (virtual private network) tunnel with the Ellucian Data Center that host our Banner systems.  As the VPN appliances are redundant, the VPN should not drop but we are performing this during our maintenance window to minimize the impact should an unexpected service interruption take place.

We will be upgrading our PaperCut system between 7 and 9 am.  During this period individual print servers that include Willow, Spruce, Bombay, Aspen, Beach and Walnut will be upgrade and will require a service interruption of approximately 10 minutes each.  Additionally, there will be about a 10 minute interruption to the web print service.  Individual print release stations will each need to be restarted as part of this process.  Any print jobs submitted to the print services will be queued up and will print once all of services are restored to normal operations.

We will upgrading the server infrastructure that hosts Concerto, a digital assets management system (https://concerto.middlebury.edu), between 9 and 9:30 am and expect a service interruption of approximately 10 minutes.

As always we appreciate your patience as perform essential systems and network maintenance and strive to keep services interruptions to a minimum.

Best regards,

Jim
