Late last night all connectivity to the Digital Media Zone in 10 Dundas, along with the AMC Theatres, and the Bookstore was lost. It was determined and confirmed this morning via a site visit that somewhere in an underground tunnel the fiber links to all these locations has been severely damaged or severed.
Although Ryerson has a high degree of network redundancy we do not have have fiber redundancy to all the switches in all buildings.
We do not have an estimated time to repair at this time and apologize for the disruption this outage will cause.
