a first router, comprising at least one processing circuit and memory, operatively connected to the at least one processing circuit, the first router being configured to:
determine that a route to a resource is to be cloaked;

retain the route in storage;
determine whether a sufficiency criterion is met, wherein the determining whether a sufficiency criterion is met comprises determining whether at least a plurality of petitions have been received by the first router, wherein the plurality of petitions supports resuming the route; and
