The president and CEO of Rogers Communications has apologized for a serious network outage that disrupted service for more than 10 million Canadians. The “network system failure” was caused by a maintenance upgrade, he says.
Tony Staffieri said there was “a maintenance upgrade in our core network, and that caused our routers to malfunction.”
As a result, some “routers erroneously flooded the network with traffic.”
