Claim Text:
1. A method, comprising: receiving, by a particular node in a computer network, electrical power from a grid source; determining, by the particular node, routing metrics to a plurality of neighbor nodes of the particular node in the computer network; determining, by the particular node, power grid connectivity of the plurality of neighbor nodes, wherein determining the power grid connectivity of the plurality of neighbor nodes includes determining which transformer sources electrical power for each of the plurality of neighbor nodes or determining which polyphase electrical system acts as the grid source for each of the plurality of neighbor nodes; routing, by the particular node, traffic from the particular node to one or more select neighbor nodes having preferred routing metrics; detecting a power outage condition at the particular node; in response to the power outage condition, routing, by the particular node, traffic from the particular node to one or more select neighbor nodes having diverse power grid connectivity from the particular node; and returning to routing traffic from the particular node to the one or more select neighbor nodes having preferred routing metrics in response to an end of the power outage condition.
