Earlier this year, Canada's telecom regulator directed Canadian carriers to report major network outages within two hours. The rules, which were put in place on an interim basis while the regulator studies the issue, followed last year's widespread outage at Rogers Communications Inc., which left millions of customers without cellphone, internet or home phone service. Although the outage was caused by a coding error, and not by a weather event, it thrust network reliability into the spotlight. (Rogers did not specify the financial impact of climate change on its operations.)
