Partial network outage in College Park: May 31, 2019

Posted on May 31, 2019 by Brian Lesser

Around 3:10 am two fibre data links experienced problems. The link that connects the main campus to TRS failed and the link to College Park (CPK) partially failed. There was no impact in TRS because Ryerson has another fibre link to TRS. The partial damage to the CPK link resulted in the loss of some network services. Roughly 60% of wireless services are still working in the building.

The problem is a result of a fire in a Hydro One cable chamber. The fire is out and the fibre vendor is waiting for permission to enter the chamber to repair the fibre.

Update: Sunday June 2, 2019 at 17:00. The fibre links have been restored by the vendor.
