"The city of Morgan Hill and parts of three counties lost 911 service, cellular mobile telephone communications, land-line telephone, DSL internet and private networks, central station fire and burglar alarms, ATMs, credit card terminals, and monitoring of critical utilities. In addition, resources that should not have failed, like the local hospital's internal computer network, proved to be dependent on external resources, leaving the hospital with a "paper system" for the day." (continues in the article).
To summarise, it's all very well having redundant systems but if someone takes to the telco infrastructure you still need something that's entirely distinct. Otherwise you end up in a wee bit of a pickle. It's a good case, as if further ones were needed, against BPL. If the power's up but the telco networks are down, interference with ham radio is a "bad thing"[tm].
