Several hundred thousand UK broadband users found themselves unable to connect to the net yesterday. Some speculated that the outage might be due to some devastating attack by cyber-baddies. But the truth according to BT was rather more mundane: a failure in a single router. Things have reportedly settled down now, and the network has returned to normal operation. But there remains a big question, which Ive seen from readers of this site and on social media. Should a company as big as BT, with all of its resources, have such a critical single point of failure?”]
