1. A method, including:
at a machine in a computer network that has a plurality of nodes, wherein each node of the plurality of nodes comprises a computational machine and has a defined location in a linearly ordered communication orbit comprising said plurality of nodes:
transmitting, via the linearly ordered communication orbit, one or more requests to a plurality of recipient nodes in a first subset of the plurality of nodes;
wherein the one or more requests cause the computational machine of each recipient node of the plurality of recipient nodes to:
locally evaluate a set of local environment verification tests to produce test results for the computational machine at the recipient node;
receiving, via the linearly ordered communication orbit, from the plurality of recipient nodes, test results locally generated by and sent by the computational machines of the plurality of recipient nodes;
automatically determining remedial actions for at least one of the plurality of nodes;
providing, for display, a data visualization representing the one or more automatically determined remedial actions for at least one of the plurality of nodes.
