A wireless mesh network here would have helped as a redundancy mechanism – although even assuming that there was a saturation of nodes in place (and as far as I know there would be lucky to be half a dozen advertised open networks) to cover that sort of area is beyond the capability of a mesh network if there were no gateways in that region and the entire mesh was running off the closest gateway nodes to the communication blacked-out area; Meraki advises no more than 10 hops off a gateway, so with 200 metre range Meraki Outdoor units you could at best cases penetrate 2km into a suburb that has no gateway nodes operational. But still – that’s better than nothing. That could have reduced the number of affected homes and businesses by 20% in this case.

Just to illustrate another benefit of wireless mesh networks.
