Network upgrade

UToday HomeNovember 29, 2012

Please be advised there will be a 48-hour campus-wide network outage from 7 a.m. on Wednesday, Dec. 26 to 7 a.m. on Friday, Dec. 28.

The Network Renewal program is fundamentally changing the university’s network architecture from a design prone to single points of failure, to a modern, redundant, high performance network. This requires significant changes to our existing device configurations. While many changes are applied with minimal user impact, some changes will require IT to take major systems offline.

Over the course of the next month, some services will be moved to the new core for initial testing. Scheduling outage windows to move services to the core is very challenging given the 24/7, 365-days-a-week nature of the university. To minimize disruption to the university community, the major two-day network outage will occur over the Christmas break.

All IT services and applications will be unavailable during this scheduled outage window, including, but not limited to the following: University email and calendar service, myUofC Portal, Blackboard, PeopleSoft, VoIP phones, Enterprise Reporting services, Internet connectivity (both wired and wireless), and university hosted web pages. IT is working to ensure that email received during the outage will be queued and delivered once all services are restored.

An additional two-day outage will also be required in 2013 to complete the move of the primary production data centre to the new core. Scheduled brief outages in the early mornings and late evenings in various parts of campus will also occur periodically, and will be ongoing until the program is complete.

“Our dedicated staff is putting in countless hours preparing for the outage. Preparations include scheduling the numerous components of the shutdown, installation, and testing of new components, automating many aspects of the shutdown and restart process, and developing pre- and post-test plans,” said Doug Doran, director of Infrastructure Services. “While the work is very technically and logistically complex, I am confident that we have taken the necessary steps to ensure a smooth transition to the new network core.”

Prior to leaving for the holidays, ensure all documents are saved, and that your desktop computer is powered off.
