A dumb, fragile system crashes and millions are impacted:
Rogers services appear to be coming back online, after a daylong outage at the telecom giant that left millions of Canadians without internet and cellular service, while also disrupting government services and payment systems.
It's logical that Rogers customers couldn't use their telephone or internet services. However, Canadians who have nothing to do with Rogers couldn't use their bank debit cards in grocery stores, restaurants, taxis, etc.
It gets worse:
Rogers-owned flanker brands like Fido and Chatr also went offline, as did services not directly controlled by Rogers, such as emergency services, travel and financial networks. [...]
Government services including already bottlenecked passport offices, Service Canada, Public Services and Procurement Canada and the Canada Revenue Agency are also affected.
It would be easier to list services that weren't affected. The Internet traffic in Canada declined by 25% because of this outage. Rogers has been making sweet profits for decades thanks to their market power in Canada. Yet, they couldn't build a robust system. It's time for the fat cats to lose weight.
